The Ambassador Theatre is a Broadway theatre located at 219 West 49th Street between Broadway and 8th Avenue in Midtown Manhattan. Designed by architect Herbert J. Krapp for the Shuberts, the structure is noteworthy in that it is situated diagonally on its site to fit the maximum number of seats possible. Its external appearance, indistinguishable from many other Broadway houses, does not hint at the unusual layout within. The building has been designated a New York City landmark.
