Every MLS Derby and Rivalry: The Complete 2026 Guide

Major League Soccer in 2026 has 30 teams spread across the United States and Canada. Among those 30 clubs, more than a dozen recognized derbies and rivalries have developed --- some inherited from decades of regional antagonism, some manufactured by the league's expansion strategy, and a few that erupted organically from the very first kickoff.

Understanding MLS derbies requires understanding what makes a derby different from a regular matchup. Not every game between two nearby clubs qualifies. Geography is the starting point, but a real derby demands more: history, stakes, mutual contempt, and an atmosphere that is visibly and audibly different from a standard regular-season match.

This is the complete inventory of every MLS derby as of the 2026 season, organized by region, with the history and stakes of each one.

What Makes an MLS Derby?

Before cataloging every derby, it is worth defining the term. In European football, a "derby" traditionally refers to a match between two clubs from the same city or metropolitan area: Manchester United vs. Manchester City, AC Milan vs. Inter, Real Madrid vs. Atletico Madrid. The term has broadened over time to include regional rivalries between clubs in neighboring cities or states.

In MLS, derbies fall into several categories:

Same-city derbies: Two clubs sharing a metropolitan area. Examples: LAFC vs. LA Galaxy (El Trafico), NYCFC vs. NY Red Bulls (Hudson River Derby).

Regional derbies: Clubs from neighboring cities or states with overlapping fan bases. Examples: Portland vs. Seattle (Cascadia), Columbus vs. Cincinnati (Hell is Real).

Cross-border derbies: Matches between US and Canadian clubs. Examples: Seattle vs. Vancouver (Cascadia), Portland vs. Vancouver (Cascadia).

Manufactured/league-branded derbies: Matchups the league promotes as rivalries, sometimes before the clubs' fans have fully embraced the narrative. Some of these develop into genuine rivalries; others remain marketing exercises.

The distinction matters because not all rivalries are created equal. El Trafico and the Cascadia Cup are genuine, deep-seated rivalries where the atmosphere, intensity, and stakes are elevated well beyond a normal match. A "rivalry" between two expansion clubs that have played each other four times does not carry the same weight, regardless of what the league's marketing department says.

The Major Derbies

El Trafico: LAFC vs. LA Galaxy

Region: Los Angeles, California First MLS meeting: March 31, 2018 Named by: Fans (reference to LA traffic)

El Trafico is the most explosive rivalry in MLS. It has everything: the largest media market in the US, star power on both rosters, a genuine cultural divide between the clubs' fan bases, and a history of dramatic, high-scoring matches that has already produced more memorable moments in six years than most rivalries generate in twenty.

The rivalry's foundation is the city itself. The LA Galaxy, based in Carson (south LA County), represented Los Angeles soccer for two decades before LAFC arrived. LAFC, based at BMO Stadium near downtown LA, positioned itself as the urban, authentic, supporters-driven alternative to the Galaxy's suburban, corporate identity.

The on-field product has been extraordinary. El Trafico matches average more goals per game than any other rivalry in MLS. The 2022 MLS Cup final between these two clubs --- Gareth Bale's 128th-minute header, the penalty shootout, the full emotional spectrum compressed into 130 minutes --- was the greatest single match in league history.

Key stat: Over 4.0 goals per game average across all El Trafico matches.

Cascadia Cup: Portland Timbers vs. Seattle Sounders vs. Vancouver Whitecaps

Region: Pacific Northwest (Oregon, Washington, British Columbia) First meetings: 1975 (NASL), 2004 (USL), 2011 (all three in MLS) Trophy: Supporter-created Cascadia Cup (awarded since 2004)

The Cascadia Cup is the most culturally significant rivalry in MLS and the only three-way derby in the league. The rivalry predates MLS involvement by decades --- Portland and Seattle have been playing each other since the NASL in the 1970s, and the USL-era matches in the 2000s were some of the best-attended lower-division games in American soccer history.

The Portland-Seattle axis is the most intense leg of the triangle. Providence Park and Lumen Field produce atmospheres that rival anything in North American sports when these two meet. The Timbers Army and Emerald City Supporters have set the standard for organized support in MLS.

Vancouver adds a cross-border dimension and prevents the rivalry from being a simple binary. The Whitecaps' relationship with both Portland and Seattle is less heated than the Portland-Seattle pairing but still carries genuine regional pride.

The Cascadia Cup itself --- a trophy created and maintained by supporter groups, not the league --- is awarded based on aggregate results across the season. It is one of the few supporter-created trophies in North American sports that carries real weight.

Hudson River Derby: NYCFC vs. New York Red Bulls

Region: New York metropolitan area First MLS meeting: May 10, 2015 Named by: Media/fans (reference to the Hudson River)

The Hudson River Derby pits two fundamentally different visions of soccer in America's largest city. NYCFC, backed by City Football Group and playing in a baseball stadium (with a long-promised soccer-specific stadium still in development), represents global football capital. The Red Bulls, owned by the energy drink company and playing in Red Bull Arena in Harrison, New Jersey, represent the corporate-branded model.

The rivalry's dynamics shifted decisively when NYCFC won MLS Cup in 2021 --- something the Red Bulls, despite existing since the league's founding (originally as the MetroStars), have never done. That trophy gap drives much of the rivalry's current emotional charge.

The atmosphere in Hudson River Derby matches is excellent, particularly at Red Bull Arena, where the South Ward supporters create a hostile environment. NYCFC's games at Yankee Stadium have a different feel --- constrained by the baseball venue's awkward sightlines but energized by a passionate core of supporters.

Hell is Real: Columbus Crew vs. FC Cincinnati

Region: Ohio (Columbus and Cincinnati, connected by I-71) First MLS meeting: March 17, 2019 Named by: A roadside billboard on I-71

Hell is Real is named after a giant yellow billboard on Interstate 71 between Columbus and Cincinnati that reads "HELL IS REAL." The name is perfect --- strange, memorable, and impossible to confuse with any other rivalry.

The rivalry has developed rapidly since FC Cincinnati joined MLS in 2019. The Columbus Crew, one of MLS's charter clubs and two-time MLS Cup champions, represent the league's old guard. Cincinnati, with their explosive fan base and impressive TQL Stadium, represent the new wave. Both clubs have been competitive in recent years, which has added genuine stakes to every meeting.

The I-71 corridor connecting the two cities creates a real geographic tension. Fans make the two-hour drive for away matches, supporter groups organize travel, and the atmosphere at both Lower.com Field and TQL Stadium is elevated for derby matches.

The Original Rivalry: LA Galaxy vs. San Jose Earthquakes (Cali Clasico)

Region: California First MLS meeting: 1996 (founding season) Also known as: California Clasico, Cali Clasico

The Cali Clasico is MLS's oldest rivalry, dating back to the league's very first season. The LA Galaxy and San Jose Earthquakes have been playing each other since 1996, and their rivalry encompasses two eras of American soccer.

Atlantic Cup: New York Red Bulls vs. D.C. United

Region: East Coast (New York/New Jersey and Washington, D.C.) First MLS meeting: 1996 (founding season) Trophy: Atlantic Cup (league-created)

The Atlantic Cup is one of the original MLS rivalries, born from the league's founding season when the MetroStars (now Red Bulls) and D.C. United were the two marquee East Coast clubs. D.C. United's early dominance --- four MLS Cup titles in the league's first eight seasons --- created a clear power dynamic that the MetroStars/Red Bulls have been trying to reverse ever since.

The rivalry has cooled somewhat as both clubs have been displaced from the top of the Eastern Conference by newer entrants like Atlanta, Cincinnati, and Columbus. But the historic weight of the matchup and the proximity of the two markets keep it relevant.

Rocky Mountain Cup: Colorado Rapids vs. Real Salt Lake

Region: Mountain West (Denver and Salt Lake City) First MLS meeting: 2005 Trophy: Rocky Mountain Cup (league-created)

The Rocky Mountain Cup is a geographically logical rivalry between the two clubs in the Mountain West. Colorado and Real Salt Lake are separated by about 500 miles of I-70, and the matchup has produced some genuinely heated moments, including several playoff encounters.

The rivalry is not as intense or well-attended as the coastal derbies, but it is a genuine regional rivalry with a trophy, consistent fan engagement, and a history that now spans two decades.

Texas Derby: FC Dallas vs. Houston Dynamo

Region: Texas First MLS meeting: 2006 Also known as: El Capitan

The Texas Derby is the rivalry between FC Dallas and the Houston Dynamo, the two longest-running MLS clubs in Texas. The addition of Austin FC in 2021 created a three-way Texas soccer landscape, but the FC Dallas-Houston matchup remains the primary derby.

The rivalry has history --- the Dynamo won back-to-back MLS Cups in 2006 and 2007, establishing an early power dynamic --- but has struggled for intensity in recent years as both clubs have gone through rebuilding phases. When both teams are competitive simultaneously, the Texas Derby is compelling. When they are not, it fades into the background.

Austin FC's arrival has added a new dimension. The Austin-Dallas matchup, in particular, has developed heat quickly, driven by Austin's rapid growth and FC Dallas's status as the established Texas club.

Trillium Cup: Toronto FC vs. Columbus Crew

Region: Cross-border (Ontario and Ohio) First MLS meeting: 2007 Trophy: Trillium Cup (named after Ontario's provincial flower)

The Trillium Cup is a cross-border rivalry that has produced some memorable matches, including their 2017 Eastern Conference Championship series. Toronto FC's 2017 treble season (Supporters' Shield, MLS Cup, Canadian Championship) included a dramatic playoff victory over Columbus that cemented the rivalry's competitive stakes.

The matchup has less geographic logic than some derbies --- Toronto and Columbus are about 450 miles apart --- but the competitive history and playoff encounters have given it genuine weight.

I-70 Derby: Sporting Kansas City vs. St. Louis CITY SC

Region: Missouri/Kansas (Kansas City and St. Louis) First MLS meeting: 2023 Named by: Interstate 70 connecting the two cities

The I-70 Derby is one of MLS's newest rivalries, dating only to St. Louis CITY SC's expansion season in 2023. The geographic logic is strong --- Kansas City and St. Louis are connected by I-70 and have a long history of sports rivalry across the NFL, MLB, and NCAA.

The early returns have been promising. St. Louis's impressive debut season, their sold-out CITYPARK stadium, and the existing cross-state antagonism have given the rivalry a running start. Whether it develops into a top-tier MLS derby depends on whether both clubs are competitive simultaneously over the next several years.

I-85 Derby: Atlanta United vs. Charlotte FC

Region: Southeast (Atlanta and Charlotte) First MLS meeting: 2022 Named by: Interstate 85 connecting the two cities

The I-85 Derby between Atlanta United and Charlotte FC is a natural geographic pairing between two of the best-attended clubs in MLS. Both play in NFL-scale stadiums (Mercedes-Benz Stadium and Bank of America Stadium), both draw massive crowds, and the I-85 corridor between the two cities is a well-traveled route.

The rivalry is young --- Charlotte only joined MLS in 2022 --- but the ingredients are there. Both clubs need sustained competitive overlap to push this from "logical matchup" to "genuine derby."

Canadian Classique: Toronto FC vs. CF Montreal

Region: Canada (Ontario and Quebec) First MLS meeting: 2012 Also known as: 401 Derby (Ontario section), Canadian Classique

The Canadian Classique is the oldest all-Canadian rivalry in MLS, predating the Vancouver Whitecaps' entry into the league. Toronto FC and CF Montreal represent the English-French cultural divide in Canada, adding a linguistic and cultural dimension that no other MLS rivalry can match.

The rivalry has produced some memorable matches, particularly in the Canadian Championship, where the stakes are heightened by the winner earning a Concacaf Champions League berth.

Southern Derby: Atlanta United vs. Orlando City

Region: Southeast (Atlanta and Orlando) First MLS meeting: 2017 Named by: Fans

Atlanta United and Orlando City entered MLS within two years of each other (Orlando in 2015, Atlanta in 2017) and immediately became the two flagship clubs of the Southeast. The rivalry was fueled by Orlando's frustration at being overtaken --- Orlando was first to MLS but Atlanta quickly surpassed them in attendance, trophies, and national attention.

The matchup has mellowed somewhat as both clubs have gone through managerial and roster transitions, but the geographic proximity and competitive history keep it alive.

Emerging and Secondary Derbies

Several newer matchups are developing into potential derbies but have not yet established the history needed to qualify as full rivalries:

Pacific Northwest Extension: Seattle Sounders vs. LAFC

Not a derby in the traditional geographic sense, but Seattle vs. LAFC has developed genuine competitive animosity. Their playoff encounters and the quality of play on both sides have elevated this matchup beyond a standard regular-season game.

Florida Derby: Inter Miami vs. Orlando City

The two Florida clubs have a natural geographic rivalry, amplified by Inter Miami's Messi-era star power and Orlando City's status as the state's original MLS club. The rivalry is still developing but has the ingredients --- same state, competing fan bases, travel-friendly distance --- to become a genuine derby.

Midwest Rivalry: Chicago Fire vs. Columbus Crew

A dormant rivalry from the league's early years that could be reignited if the Chicago Fire can return to sustained competitiveness. The two clubs played meaningful matches in the late 1990s and early 2000s but have not been competitive simultaneously in recent years.

California Cup: LA Galaxy vs. LAFC vs. San Jose Earthquakes

The three California clubs form a potential triangle rivalry, though in practice the LA clubs' rivalry with each other (El Trafico) is far more intense than either club's rivalry with San Jose.

How the League Promotes Derbies

MLS actively promotes rivalry matchups through several mechanisms:

Rivalry Week: A dedicated matchweek (typically multiple rounds throughout the season) where the schedule is structured to feature all major rivalry pairings simultaneously. Rivalry Week gets additional marketing support, special broadcast treatment, and enhanced digital content.

Trophy matches: League-created trophies like the Atlantic Cup, Rocky Mountain Cup, and Trillium Cup give tangible stakes to rivalry matchups. The supporter-created Cascadia Cup predates and outshines most league-created trophies.

Schedule protection: The league ensures that rival clubs play each other at least twice per season (home and away), even when divisional scheduling might otherwise reduce inter-conference matchups.

For coverage of MLS Rivalry Week and its impact on the season, see the MLS Rivalry Week explainer.

What Makes a Great MLS Derby

Looking across all of these matchups, the best MLS derbies share common traits:

Geographic proximity: The shorter the drive between stadiums, the better. Same-city rivalries (El Trafico, Hudson River) and short-corridor rivalries (Hell is Real, Cascadia) generate the most travel and the most hostile away atmospheres.
Competitive balance: Rivalries die when one side dominates for too long. The best derbies feature stretches where both clubs are playoff-caliber, with the head-to-head record staying close enough that every match feels consequential.
Cultural contrast: The most compelling rivalries feature clubs with genuinely different identities. LAFC vs. Galaxy (urban vs. suburban), NYCFC vs. Red Bulls (Manhattan vs. New Jersey), Portland vs. Seattle (counter-culture vs. tech-city) --- these contrasts give fans something to argue about beyond the scoreline.
History: You cannot manufacture history. The Cascadia Cup carries weight because it spans decades. El Trafico carries weight because of the 2022 MLS Cup final. Time and memorable moments are what transform a matchup into a rivalry.
Fan investment: Ultimately, a derby is only as real as the fans make it. When supporters organize travel for away matches, create rivalry-specific tifos, and treat derby day as the most important match on the calendar, the rivalry is real. When they do not, it is just another game.

MLS in 2026 has a richer derby landscape than at any point in its history. The league's expansion from 10 to 30 teams has created geographic clusters and competitive overlaps that generate natural antagonism. Not every manufactured rivalry will stick, but the ones that do --- El Trafico, Cascadia, Hell is Real, the Hudson River Derby --- are among the best in North American sports.
