The Capital Athletic Conference (CAC) is an intercollegiate athletic conference affiliated with the NCAA's Division III. Member institutions are located in the eastern United States in the states of Maryland, Pennsylvania, and Virginia.
Formed in 1989, the charter members were The Catholic University of America, Gallaudet University, the University of Mary Washington, Marymount University, St. Mary's College of Maryland, and York College of Pennsylvania. Goucher College joined the CAC in 1991, followed by Salisbury University in 1993. Hood College, Stevenson University, and Wesley College all formally joined the conference for the 2007–08 season, although Hood and Stevenson had already joined for some sports in the 2006–07 season. CUA and Goucher College left the conference in 2007–08 to become members of the new Landmark Conference. Gallaudet left the conference after the 2009-10 season for the North Eastern Athletic Conference (NEAC) for some sports. Stevenson and Hood left the CAC for the Middle Atlantic Conferences effective July 1, 2012. The CAC added three members on July 1, 2013: Christopher Newport University, Penn State Harrisburg, and Southern Virginia University. Southern Virginia transitioned from the National Association of Intercollegiate Athletics (NAIA) and became eligible for conference championships in the 2014–15 season.
The CAC lost two members at the end of the 2017–18 school year with Marymount and Wesley leaving to become charter members of the new Atlantic East Conference. Two more members are set to leave after the 2018–19 school year. Frostburg State announced that it planned to transition to NCAA Division II and join the Mountain East Conference, pending NCAA approval. Penn State Harrisburg, which left the NEAC to join the CSAC in 2013, will return to its prior conference home. The CAC will lose another member in 2019–20 when York leaves for the MAC Commonwealth Conference.
