List of Major League Soccer seasons

[3] The champion is determined by the MLS Cup and its playoffs, a postseason knockout tournament for the top teams in the regular season similar to those for other North American sports leagues.

[4][5] MLS has an average attendance of over 23,000 spectators at regular season matches and reached over 11 million total in 2024—among the highest for soccer leagues globally.

[13][14] As of 2024[update], 22 of the league's 29 teams play in soccer-specific stadiums that range in capacity from 18,000 to 30,000 seats, while others use larger shared venues.

[12] MLS teams each play 34 matches during the regular season, which runs from February to October, primarily between opponents in the same conference.

[15][16] The league adopted an unbalanced schedule with heavier emphasis on intra-conference matches in 2012 due to the growing number of teams and the impact of travel for players.
