The thirteenth season of the American animated television series The Simpsons originally aired on the Fox network between November 6, 2001, and May 22, 2002, and consists of 22 episodes. The showrunner for the thirteenth production season was Al Jean, who executive-produced 17 episodes. Mike Scully executive-produced the remaining five, which were all hold-overs that were produced for the previous season.

The show is set in the fictional city of Springfield, and lampoons American culture, society, television and many aspects of the human condition.
