Baylor Bears (variously Baylor or BU) refers to the sports teams of Baylor University. Baylor's men's sports teams are nicknamed the Bears, and some women's teams are nicknamed the Lady Bears. Student athletes participate in the NCAA's Division I, and Baylor is the only private school in the Big 12 Conference. Prior to joining the Big 12, Baylor was a member of the Southwest Conference from the conference's charter in 1914 until its dissolution in 1996.

Baylor won its first team NCAA title in 2004 as the men's tennis team defeated UCLA in the championship game. They narrowly lost to UCLA in the 2005 national championship match. The Women's Basketball team won the school's other NCAA Championship in 2005.

The mascots of Baylor University are two black bears named Joy and Lady.
