The Southeastern Theoretical Chemistry Association (SETCA) is a loose organization of theoretical and computational chemists from across the Southeastern United States. Since its inception in 1970 by Prof. Bruno Linder of Florida State University, its primary function has been an annual conference to give faculty, students, and postdoctoral associates an opportunity to present their most recent research results.

The University of Mississippi hosted the annual SETCA meeting in 2017 and 2004.
