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.
Some smaller theaters still continue this tradition, and a few summer stock theaters have become highly regarded by both patrons as well as performers and designers. Often viewed as a starting point for professional actors, stock casts are typically young, just out of high school or still in college.
