The 2010 MLS Cup Playoffs was the postseason tournament subsequent to Major League Soccer's 2010 season.
The playoffs began on October 30, with the Los Angeles Galaxy defeating the Seattle Sounders FC in the quarterfinal-round. Three weeks later, the Colorado Rapids defeated FC Dallas 2-1 in the Cup final at BMO Field in Toronto, Ontario. It was Colorado's first title and second MLS Cup final appearance, and it was FC Dallas's first appearance in an MLS Cup final.
Of the eight MLS clubs to earn qualification into the tournament, only four of them qualified the season before; Columbus Crew, Los Angeles Galaxy, Seattle Sounders FC, and the defending-champions, Real Salt Lake. The San Jose Earthquakes were making their first playoff appearance since 2005, Dallas' since 2007. It was Colorado's and New York Red Bulls's first time since 2008.
