Hayes Gymnasium, completed in 1910, is the oldest section of the current Arvin Cadet Physical Development Center at the United States Military Academy.
 Originally built as an independent structure to replace the Academy's previous Richard Morris Hunt-built gymnasium which had served between 1891 and 1910, it was part of a large contract bid awarded to the Boston architectural firm of Cram, Goodhue, & Ferguson in 1903.

Formerly the East Gym, it was renamed in 1989 for 1st Lt. (
posthumously promoted Captain) Thomas Jay Hayes IV, Class of 1966, killed in action in Vietnam on April 17, 1968.
