MS Sea Witch was a United States Maritime Commission type C2 cargo ship, the first of four pre-war hulls, built by Tampa Shipbuilding & Engineering Company, Tampa, Florida and delivered in July 1940. The ship was of the basic C2 design, rather than the more numerous C2-S, C2-S-A1, C2-S-B1 types and four C2-T hulls delivered December 1941 through March 1942. Sea Witch was one of the relatively few C2 types built with diesel engines.
