The Conference USA or C-USA is a collegiate athletic conference that covers the Southern part of the United States. The members of the Conference USA compete in all sports divisions of the National Collegiate Athletic Association (NCAA) Division I. The Conference USA is headquartered in Las Colinas in Dallas, Texas.

The Conference USA started from the Great Midwest Conference and Metro Conference merger in 1995. To complete its 12 members, the conference invited University of Houston to become a member but since UH was still committed to Southwest Conference during that time, they could not join C-USA immediately. Hence, the conference participated in all sports except football, which only started a year later.

Current members of the East Division of the Conference USA are University of Alabama at Birmingham (Blazers), University of Central Florida (Knights), East Carolina University (Pirates), Marshall University (Thundering Herd), University of Memphis (Tigers), and University of Southern Mississippi (Golden Eagles). Current members of the West Division of the Conference USA are University of Houston (Cougars), Rice University (Owls), Southern Methodist University (Mustangs), University of Texas at El Paso (Miners), Tulane University (Green Wave), and University of Tulsa (Golden Hurricane).

Members of the Conference USA participate in baseball (men’s division), basketball (men and women’s division), cross country (men and women’s division), football (men’s division), golf (men and women’s division), rowing (women’s division), soccer (men and women’s division), softball (women’s division), tennis (men and women’s division), swimming (men and women’s division), indoor track and field (men and women’s division), outdoor track and field (men and women’s division) and volleyball (women’s division).
