In American theater, summer stock theater is a theater that presents stage productions only in the summer. The name combines the season with the tradition of staging shows by a resident company, reusing stock scenery and costumes. Summer stock theaters frequently take advantage of seasonal weather by having their productions outdoors, under tents set up temporarily for their use, or in barns.

A repertory theatre, also called repertory, rep, true rep or stock, which are also called producing theatres, is a theatre in which a resident company presents works from a specified repertoire, usually in alternation or rotation.
