The 2027-28 MLS regular season will begin in mid-to-late July 2027 and conclude with the Audi MLS Cup Playoffs and MLS Cup presented by Audi in late May 2028.
Like other major international leagues, MLS will observe a midwinter break from mid-December through early February, with no league matches scheduled in January.
Before the calendar change, MLS will stage a transition season from February to May 2027, featuring a 14-game regular season, playoffs, and MLS Cup. Those results will determine 2027 qualification for the Lamar Hunt U.S. Open Cup, Canadian Championship, Leagues Cup, and Concacaf Champions Cup.
