The MLS Cup Playoffs will begin on October 19, and conclude with the MLS Cup 2019 on November 10, under a new format that differs from previous seasons. The playoffs will use single-match rounds and include 14 teams.

FC Cincinnati joined the league as an expansion franchise, bringing the total number of clubs to 24. Minnesota United FC plans to open their first soccer-specific stadium, Allianz Field, on April 13.

Atlanta United FC are the defending MLS Cup champions, while New York Red Bulls are the defending Supporters' Shield winners.

Stadiums and locations
The Portland Timbers announced in late 2018 that, due to expansion construction at Providence Park, they will play the first 12 games of the 2019 season on the road. The construction, which adds about 4000 seats (bringing the total capacity to just over 25,000), also includes a completely remodeled east side of the stadium, an updated concourse and concession stands on the west side of the stadium, a new scoreboard, ribbon boards and video board, and new turf. The stadium is expected to be ready to host MLS games in May or June 2019. The first home game for Portland in their renovated stadium is scheduled to be held on June 1, 2019, against Los Angeles FC.
