American Athletic Conference
Two schools left The American after spending only the 2013–14 school year in the renamed conference. Before 2013, both had been members of the original Big East. A third school left The American in 2020 to rejoin most of its historic all-sports rivals in the current Big East. Three more schools left for the Big 12 in 2023, one of which stayed in The American for women's lacrosse only.
