1970 Chicago White Sox season

The 1970 Chicago White Sox season was the team's 70th season in the American League, and its 71st overall. They finished with a 56–106 record, their third-worst in 114 seasons of Major League Baseball, and finished in last position in the American League West, 42 wins behind the first-place Minnesota Twins.

Manager Don Gutteridge was fired September 1 with the team 49–87. Bill Adair served briefly as interim manager before Chuck Tanner, manager of the White Sox' Class AAA affiliate in Hawaii, came to the mainland to assume the position with the parent club. Tanner went 3–13 to close 1970 and remained skipper on the South Side through 1975.

The White Sox drew a paltry 495,355 fans to Comiskey Park, the lowest total in Major League Baseball.

The lone bright spot of 1970 was the hiring of organist Nancy Faust, who was a fixture at Comiskey and its successor, U.S. Cellular Field, for 40 years..

This was their last season of 100 losses or more until 2018, when they reached the century mark on the final day of the season.
