The 2026 Major League Soccer (MLS) season marks the league's 31st year, featuring 30 clubs split evenly into Eastern and Western Conferences, with the regular season running from February 21 to November 7. A unique highlight is a six-week break (May 25–July 16) to accommodate the 2026 FIFA World Cup, which is being co-hosted by the United States, Canada, and Mexico. This season is historically significant as the final full campaign under the traditional spring–autumn calendar, as MLS will transition to a summer–spring schedule starting with the 2027–28 season. All matches are broadcast on Apple TV, replacing the previous MLS Season Pass, while Inter Miami CF enter as defending MLS Cup champions and the Philadelphia Union hold the Supporters' Shield. For the first time in over two decades, no expansion team joins the league, though Inter Miami opened their new home, Nu Stadium, on April 4, 2026. The postseason playoffs will culminate in MLS Cup 2026 on December 18, concluding an unprecedented year shaped by the World Cup break and a major scheduling overhaul.
