The 2011 MLS season was a landmark year that featured 18 teams competing in the league's 16th season. The regular season ran from March 15 to October 23, with each team playing 34 games. This season marked significant expansion as the league continued its growth trajectory with Vancouver Whitecaps FC and Portland Timbers joining as the newest franchises.
The Los Angeles Galaxy dominated the season, winning both the Supporters' Shield for the best regular season record (19-5-10) and MLS Cup 2011. The Galaxy's championship run was highlighted by the signing of David Beckham in his final season and the emergence of Landon Donovan as a key playmaker. They defeated the Houston Dynamo 1-0 in the MLS Cup final at the Home Depot Center (now Dignity Health Sports Park).
Individual honors went to Dwayne De Rosario of D.C. United, who won the MLS MVP award after scoring 16 goals and adding 11 assists. Chris Wondolowski of the San Jose Earthquakes claimed the Golden Boot with 16 goals, while Kasey Keller of the Seattle Sounders won Goalkeeper of the Year in what would be his final professional season.
The 2011 season also featured the continued growth of soccer-specific stadiums, with several teams playing in newly built or renovated venues. The league's average attendance remained strong at over 17,000 per game, reflecting the sport's growing popularity in North America.
