The 2003 Chicago White Sox season was the White Sox's 104th season. They finished with a record of 86–76, good enough for second place in the American League Central, four games behind the champion Minnesota Twins. The White Sox also hosted the 74th Major League Baseball All-Star Game on July 15.

Regular season

On April 15, 2003, a fan came out of the stands during the baseball game between the Kansas City Royals and Chicago White Sox and attacked first base umpire Laz Diaz. After Carlos Lee flied out to right to end the eighth inning, the fan ran on the field and tried to tackle Diaz, wrapping his arms around the umpire's legs.
