Hedgerow Theatre is a theatre company based in Rose Valley, Pennsylvania, near Philadelphia, founded in 1923. It was "for many years the only true U. S. professional repertory theater." The building is a contributing structure in the Rose Valley Historic District listed on the National Register of Historic Places.
Hedgerow was founded in 1923 by New York-based director and actor Jasper Deeter in Rose Valley, less than 3 miles from Media and Swarthmore. The theatre itself, originally a grist-mill built in 1840, seats 144 spectators, after a reconstruction designed by architect Will Price. It is a contributing structure in the Rose Valley Historic District. Hedgerow’s green room showcases a staircase and table designed by Wharton Esherick, acclaimed American craftsman, as well as one time set designer for Hedgerow. Located a half mile from the theatre is Hedgerow House, used as housing for the residential company members as well as a rehearsal space, school, and office, accompanied by the costume and prop shops.
During its long history, Hedgerow has helped to spawn other popular theatre companies, such as People's Light and Theatre Company. Hedgerow has been the site of many play debuts, and has received recognition by producing the plays of George Bernard Shaw, Eugene O'Neill, and Seán O'Casey. Its actors have included Richard Basehart, Ann Harding, Keanu Reeves, Stephen Lang and Austin Pendleton.
