The South 40 includes ten residential communities located at the southwest end of the Danforth Campus that serve as the home to first year students and sophomores.
The South 40 is a “small town” with its own fitness center, dining facilities, meeting rooms, basketball and sand volleyball courts, recreation and game rooms, and music practice rooms. In addition, Bear Necessities (gift shop), Paws & Go (convenience store), the Hitzeman Mail Center, printers and copiers, and several student-run businesses are located nearby.
Residence halls located on the South 40 are considered either modern or traditional buildings.
