The 2009 Chicago White Sox season was the organization's 110th season in Chicago and 109th in the American League. The Sox entered the 2009 season as the defending American League Central champions, attempting to repeat against the Cleveland Indians, Detroit Tigers, Kansas City Royals and Minnesota Twins. The White Sox finished the season 79–83 with third place in the American League Central, 7+12 games behind the AL Central champion Minnesota Twins, were officially eliminated from postseason contention for the first time since 2007, and failed to make the playoffs until the 2020 season.

On July 23 Mark Buehrle threw the eighteenth perfect game in Major League history, defeating the Tampa Bay Rays 5–0.
