Wyndham's Theatre is a West End theatre, one of two opened by actor/manager Charles Wyndham. Located on Charing Cross Road in the City of Westminster, it was designed c.1898 by W. G. R. Sprague, the architect of six other London theatres between then and 1916. It was designed to seat 759 patrons on three levels; later refurbishment increased this to four seating levels. The theatre was Grade II* listed by English Heritage in September 1960.

Sir Charles Wyndham, né Charles Culverwell, was an English actor and theatre proprietor. Wyndham's Theatre in London is named after him, and he also built the New Theatre nearby.
