The Biggest Rivalries in MLS: A Complete Ranking for 2026

What Makes an MLS Rivalry?

Not every matchup between two teams in the same region qualifies as a rivalry. Geography is necessary but insufficient. A real rivalry requires at least three of the following: shared geography that creates overlapping fan bases, a history of meaningful matches with high stakes, active supporter groups that invest emotional energy in the opposition's failure, competitive balance that prevents one club from permanently dominating, and a cultural or identity-based tension that extends beyond the pitch.

MLS, as a league that has expanded from 10 teams in 1996 to 30 teams in 2026, has seen rivalries form at different speeds. Some, like the Cascadia Cup, were inherited from lower divisions and decades of regional animosity. Others, like El Trafico, arrived fully formed in their first season. A few, like the I-70 Derby between Sporting Kansas City and St. Louis CITY SC, are still finding their footing.

What follows is a ranking of every significant MLS rivalry as of the 2026 season, ordered by intensity, history, atmosphere, and competitive stakes. For head-to-head statistics on any matchup mentioned below, visit the head-to-head records index.

1. El Trafico: LAFC vs LA Galaxy

Full guide: El Trafico: LAFC vs LA Galaxy

Why it's number one: El Trafico is the most compelling rivalry in MLS because it delivers on every dimension simultaneously. Star power, on-field chaos, narrative drama, market size, and the single greatest match in MLS history --- the 2022 MLS Cup final between these two clubs.

LAFC entered the league in 2018 as a deliberate counterpoint to the LA Galaxy: urban vs. suburban, insurgent vs. establishment, the 3252 vs. the Galaxy's two-decade brand. The rivalry produced iconic moments immediately: Zlatan's debut volley, Vela's hat trick in the 5-3 demolition, and then the 2022 Cup final, which ended with Gareth Bale heading in a 128th-minute equalizer before LAFC won on penalties.

No other MLS rivalry has an MLS Cup final between the two clubs. That alone puts El Trafico at the top.

Head-to-head: LAFC vs LA Galaxy

Key stats: Highest goals-per-game average of any MLS rivalry pairing. Consistently sold out at both venues. Multiple red cards and late winners per season.

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

Full guide: The Cascadia Cup

Why it's number two: The Cascadia Cup is the deepest, most culturally rooted rivalry in MLS. It predates all three clubs' MLS involvement, stretching back to the NASL in the 1970s and the USL in the 2000s. The supporter-created trophy, the Pacific Northwest identity, and the fact that this is a three-way rivalry rather than a simple head-to-head make it unique.

The Portland-Seattle axis is the backbone. Portland Timbers vs Seattle Sounders matches at Providence Park and Lumen Field produce some of the best atmospheres in North American sports. The Timbers Army and Emerald City Supporters have set the standard for organized support in MLS, and Cascadia derbies are the matches where they bring their absolute best.

Vancouver adds the cross-border dimension: a Canadian club competing against two American ones, with all the logistical complexity and national pride that entails.

The Cascadia Cup is the rivalry that best represents MLS supporter culture. If El Trafico is the blockbuster, Cascadia is the masterpiece.

3. Hell is Real: Columbus Crew vs FC Cincinnati

Why it's number three: Hell is Real is the fastest-growing rivalry in MLS. Named after a roadside billboard on I-71 between Columbus and Cincinnati, this rivalry started when FC Cincinnati joined MLS in 2019 and has already developed an intensity that rivals matchups with decades more history.

The Columbus Crew, one of MLS's charter clubs and two-time MLS Cup champions (2008, 2020), represent the league's old guard. FC Cincinnati represent the new: a club that built a massive following in the USL before entering MLS, constructed the stunning TQL Stadium, and has rapidly become one of the best-supported clubs in the league.

The rivalry works because of competitive balance. Both clubs have been playoff-caliber in recent seasons, and the matches carry genuine table implications. TQL Stadium and Lower.com Field both produce excellent atmospheres for derby matches. Ohio's split soccer identity --- Columbus in the center, Cincinnati in the southwest --- creates real geographic tension.

The "Hell is Real" name is perfect: absurd, memorable, and impossible to confuse with anything else.

Head-to-head: Columbus Crew vs FC Cincinnati

4. Hudson River Derby: NYCFC vs NY Red Bulls

Full guide: Hudson River Derby: NYCFC vs NY Red Bulls

Why it's number four: The Hudson River Derby has the biggest market and one of the more interesting structural tensions in MLS: NYCFC, the City Football Group-backed club playing in a baseball stadium, versus the New York Red Bulls, the corporate-named franchise with a purpose-built stadium in New Jersey.

NYCFC won MLS Cup in 2021 --- something the Red Bulls have never done despite existing since the league's founding. That inversion of expectations drives the rivalry's emotional core. The Red Bulls have the stadium, the academy, and the regular-season pedigree. NYCFC has the trophy.

The Hudson River Derby is ranked fourth rather than higher because the atmosphere, while good, is constrained by NYCFC's stadium situation. Yankee Stadium is not a great soccer venue, and it limits what the Third Rail can produce. If and when NYCFC's planned Queens stadium opens, this rivalry will likely move up in any ranking.

Head-to-head: NYCFC vs NY Red Bulls

5. Florida Derby: Inter Miami vs Orlando City

Why it's number five: The Florida Derby between Inter Miami and Orlando City has always carried genuine animosity. The two clubs are separated by roughly 230 miles of the Florida Turnpike, and the fan bases genuinely dislike each other. The rivalry started in 2020, Miami's first MLS season, and heated up immediately.

What elevated this rivalry from "solid regional matchup" to "top five nationally" was one person: Lionel Messi. When Messi joined Inter Miami in July 2023, every Miami match became an event, and the Florida Derby became the most-watched regular-season fixture in the Eastern Conference. Messi's presence drew global attention to a rivalry that was already compelling on its own merits.

Orlando's wall of purple at Exploria Stadium, the Iron Lion Firm's intensity, and the genuine on-field physicality of these matches make the Florida Derby a fixture that regularly produces memorable moments. The question going forward is whether the rivalry maintains its intensity when Messi eventually departs.

Head-to-head: Inter Miami vs Orlando City

6. Texas Derby: FC Dallas vs Houston Dynamo

Why it's number six: The Texas Derby is one of the oldest rivalries in MLS, dating back to the Houston Dynamo's founding in 2006 (the franchise relocated from San Jose). FC Dallas and the Houston Dynamo compete for soccer supremacy in the state of Texas, and the matchup has a blue-collar intensity that reflects both clubs' identities.

The Texas Derby has produced some genuinely hostile matches. The travel distance (roughly 240 miles of I-45) means that away supporter sections are smaller than in more compact rivalries, but the fans who make the trip are committed. Both Toyota Stadium (FC Dallas) and Shell Energy Stadium (Houston) become noticeably more energized for derby matches.

FC Dallas's strength has historically been their academy, which has produced a pipeline of talent that few MLS clubs can match. Houston's identity has been more about grit and opportunistic investment. The competitive balance has fluctuated, with Houston winning two MLS Cups (2006, 2007) shortly after their founding and FC Dallas reaching the Cup final in 2010.

The arrival of Austin FC in 2021 has complicated the Texas soccer landscape, creating a secondary rivalry (Austin vs Houston) that threatens to dilute the Texas Derby. But the FC Dallas-Houston matchup retains its historical significance.

Head-to-head: FC Dallas vs Houston Dynamo

7. Cali Clasico: LA Galaxy vs San Jose Earthquakes

Why it's number seven: The Cali Clasico is one of the original MLS rivalries, dating to the league's founding in 1996. The LA Galaxy and the San Jose Earthquakes are both charter members, and their rivalry encompasses the California cultural divide: Southern California glamour vs. Northern California tech-adjacent pragmatism.

The Cali Clasico was at its most intense in the early 2000s, when the Earthquakes (then playing as the San Jose Clash, later renamed) were genuine contenders and the Galaxy were the league's marquee franchise. Landon Donovan's involvement with both clubs --- he started in San Jose, became a legend in LA --- added personal stakes.

In recent years, the Cali Clasico has lost some of its edge because the competitive gap has widened. The Galaxy have remained a consistent playoff team, while San Jose has struggled. A rivalry requires competitive balance to maintain intensity, and the Cali Clasico has been lopsided in the Galaxy's favor for much of the 2020s.

It retains its ranking because of history and the California cultural tension. When both teams are competitive simultaneously, this is one of the best matchups in the league.

Head-to-head: LA Galaxy vs San Jose Earthquakes

8. 401 Derby: Toronto FC vs CF Montreal

Why it's number eight: The 401 Derby, named for Ontario Highway 401 that connects Toronto and Montreal, is the premier Canadian rivalry in MLS. Toronto FC and CF Montreal represent Canada's two largest cities and its most fundamental cultural divide: English Canada vs. French Canada.

The rivalry carries weight that extends far beyond soccer. Toronto and Montreal compete for status as Canada's cultural capital, and the linguistic and political tensions between English-speaking Ontario and French-speaking Quebec give this rivalry a depth that most MLS matchups lack.

On the field, Toronto's 2017 season --- when they won MLS Cup, the Supporters' Shield, and the Canadian Championship in a treble --- was a defining moment. CF Montreal (then the Montreal Impact) has been more inconsistent but is capable of producing hostile atmospheres at Stade Saputo, particularly against Toronto.

The introduction of the Vancouver Whitecaps created a broader Canadian Championship dynamic, but the Toronto-Montreal axis remains the most intense Canadian matchup.

Head-to-head: Toronto FC vs CF Montreal

9. Austin vs Houston: The New Texas Rivalry

Why it's number nine: When Austin FC entered MLS in 2021, the most immediate rivalry was with Houston Dynamo, 165 miles down the road. The Austin-Houston rivalry heated up faster than almost anyone predicted, driven by the cultural tension between Austin (progressive, tech-focused, rapidly growing) and Houston (industrial, diverse, established).

Q2 Stadium, Austin's home venue, quickly became one of the most hostile environments in MLS. The Verde Wall supporter section creates an atmosphere that is disproportionate to the club's short history. Houston fans, for their part, view Austin as a Johnny-come-lately --- a club that has not yet earned the right to claim Texas soccer.

The rivalry is young but genuine. As both clubs mature, this matchup has the potential to become one of the best in the league.

Head-to-head: Austin FC vs Houston Dynamo

10. Atlantic Cup: NY Red Bulls vs DC United

Why it's number ten: The Atlantic Cup between the New York Red Bulls and DC United is one of the oldest rivalries in MLS, dating to the league's inaugural 1996 season. Both clubs are charter members, and they have met in multiple playoff series over the years.

DC United's dominance in the league's early years (winning four MLS Cups between 1996 and 2004) and the MetroStars'/Red Bulls' chronic inability to win the big trophy created an early power imbalance that defined the rivalry. The Red Bulls have since become the more consistently competitive side, while DC United has entered a rebuilding phase.

The Atlantic Cup has a trophy --- supporter-created, like the Cascadia Cup --- and the matches between these two clubs carry a historical weight that newer rivalries cannot replicate. It is a rivalry that rewards fans who know MLS history.

Head-to-head: NY Red Bulls vs DC United

Honorable Mentions

Rocky Mountain Cup: Colorado Rapids vs Real Salt Lake

The Colorado Rapids and Real Salt Lake contest the Rocky Mountain Cup, a supporter-created trophy awarded since 2005. The rivalry has the geographic ingredients (Denver vs. Salt Lake City, mountain West identity) but has been hampered by periods where one or both clubs were uncompetitive. When both teams are in playoff form, the Rocky Mountain Cup produces quality matches and committed away support.

Trillium Cup: Columbus Crew vs Toronto FC

A cross-border rivalry with its own trophy, the Trillium Cup between Columbus and Toronto FC has been somewhat overshadowed by the Hell is Real Derby's rapid rise. But the Trillium Cup has history --- it has been awarded since 2009 --- and the Columbus-Toronto matchup carries genuine stakes when both clubs are competitive.

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

The newest marquee rivalry in MLS, the I-70 Derby between Sporting Kansas City and St. Louis CITY SC began when St. Louis entered the league in 2023. The 250-mile I-70 corridor connects two Missouri cities with a deep civic rivalry, and the early matches have shown promise. CITYPARK, St. Louis's stunning downtown stadium, provides an excellent venue for the home leg. This rivalry needs more time and more meaningful matches, but the foundation is strong.

Southern Rivalries: Atlanta United, Nashville SC, Charlotte FC

The growth of MLS in the American South has created a cluster of potential rivalries: Atlanta United vs Nashville SC, Atlanta United vs Charlotte FC, and Nashville SC vs Charlotte FC. None of these have fully crystallized into a top-tier rivalry yet, but the combination of geographic proximity, rapid fan base growth, and competitive investment suggests that the South will produce at least one elite rivalry in the coming years.

Atlanta United, with its massive fan base and Mercedes-Benz Stadium atmosphere, is the most likely anchor for a dominant Southern rivalry. The 2017--2018 era --- when Atlanta averaged 50,000+ fans and won MLS Cup in 2018 --- set a standard that Nashville and Charlotte are working to match.

Cross-Conference Rivalries

MLS's conference structure means that some natural rivalries occur less frequently than fans would like. Inter Miami vs LAFC, for instance, carries star-power appeal but is an inter-conference matchup that happens only once or twice per season. Similarly, Seattle Sounders vs Atlanta United --- the 2019 and 2020s match between the two highest-attendance clubs --- has the feel of a rivalry but lacks the frequency of same-conference matchups.

What the Future Holds

MLS rivalries are evolving faster than at any point in the league's history. The expansion to 30 teams has created new geographic pairings. The Apple TV deal has given every match a national platform, which rewards rivalries that produce entertaining content. The 2026 World Cup will introduce millions of new fans to MLS, and rivalries are the most effective tool for converting World Cup curiosity into sustained engagement.

Several trends are worth watching:

New-market intensity: Clubs like FC Cincinnati, Austin FC, and St. Louis CITY SC have built passionate fan bases in a remarkably short time. The rivalries involving these clubs (Hell is Real, Austin-Houston, I-70 Derby) are developing faster than historical norms.

Stadium upgrades: NYCFC's planned stadium in Queens, if completed, would instantly elevate the Hudson River Derby. Any future Galaxy stadium closer to downtown LA would do the same for El Trafico. Venue quality is a major driver of rivalry atmosphere.

Competitive parity: MLS's salary cap and roster rules create more competitive balance than most soccer leagues. This is a feature, not a bug, for rivalries: when either team can win on any given match day, every derby carries genuine stakes.

Supporter culture maturation: MLS supporter culture has grown enormously since the Cascadia clubs set the standard in the late 2000s. As supporter groups in newer markets mature, the atmosphere at derby matches will continue to improve.

The rivalries profiled here are the ones that matter in 2026. Five years from now, the ranking may look different. That is the sign of a league that is growing. For the full head-to-head database, including every historical matchup in MLS, visit the head-to-head records page.
