As of 2023, the Eastern Conference contains 15 teams. The conference has produced 17 Supporters' Shield champions and 11 MLS Cup winners in Major League Soccer's first 28 seasons. In 2000 and 2001, the conference was referred to as the Eastern Division when Major League Soccer briefly reorganized into three divisions.
Changes from 2001: The Eastern Division changed back its name to Eastern Conference following the contraction of the Miami Fusion and the Tampa Bay Mutiny, resulting in the disbanding of the Central Division; Chicago Fire and Columbus Crew moved in from the Central Division
Changes from 2020: Nashville SC moved in from the Western Conference;[6] the
Montreal Impact was renamed Club de Foot Montréal. Columbus Crew SC was briefly renamed to Columbus SC and then to Columbus Crew.
Changes from 2021: Charlotte FC was added as a then-unnamed expansion franchise in 2019, with its first season initially set for 2021[7] but delayed by a year due to the COVID-19 pandemic.[8] Nashville SC moved back to the Western Conference.[9][10]
Changes from 2022: Nashville SC was moved back to the Eastern Conference as expansion side St. Louis City SC was added to the Western Conference.[11]
Eastern Conference playoff champions by year
Note: The conference finals were a best-of-three series through 2001 (including the MLS semifinals in 2000 and 2001, when a conference playoff format was not used). Matches tied after regulation were decided by a shoot-out. In 2002, a similar format was used except that draws were allowed and the team earning the most points advanced. From 2003 through 2011, the Finals were a single match. Matches tied after regulation moved to extra time (Golden goal extra time was implemented for 2003 only), then a shoot-out if necessary. Beginning in 2012, the finals were a two-match aggregate series. The away goals rule for series that finished even on aggregate was first implemented in 2014. Extra time and shoot-outs are used if necessary, although away goals did not apply in extra time. In 2019, the playoffs returned to a single match format (including the conference finals), hosted by the higher ranked team through the regular season.
Eastern Conference regular season champions by year
No trophy is awarded for leading the conference standings at the end of the regular season, unless the regular season leader also wins the Supporters' Shield. The winner of the Conference play-offs is considered the Conference champion. Three clubs have topped the Eastern Conference standings at the end of the regular season, won the Supporters' Shield, the Eastern Conference (MLS) and the MLS Cup; D.C. United, twice, Columbus Crew and Toronto FC. Toronto in 2017 also won the Canadian Championship, being the only MLS team to therefore take a clean sweep of all titles available to them.
^ – MLS did not have draws until the 2000 season.
† – Miami Fusion were declared winners of the Eastern Division in 2001 after the September 11, 2001 terrorist attacks forced the cancellation of the rest of the regular season. The MLS Cup playoffs began on September 20.
In 1996, 1997, 1999, 2000, 2001, and 2004, the Major League Soccer All-Star Game was contested between an all-star team from the Eastern Conference and an all-star team from the Western Conference. In total, the MLS East all-star team has 4 wins, 1 draw, and 1 loss against the west.
