The Theatre Royal, Haymarket is a West End theatre in the Haymarket in the City of Westminster which dates back to 1720, making it the third-oldest London playhouse still in use. Samuel Foote acquired the lease in 1747, and in 1766 he gained a royal patent to play legitimate drama in the summer months. The original building was a little further north in the same street. It has been at its current location since 1821, when it was redesigned by John Nash.
