The Marquis Theatre is a Broadway theater on the third floor of the New York Marriott Marquis hotel in the Theater District of Midtown Manhattan in New York City, New York, U.S. Opened in 1986, it is operated by the Nederlander Organization. There are about 1,612 seats in the auditorium, spread across an orchestra level and a balcony.
The Marquis was designed by John C. Portman Jr., who designed the Marriott Marquis and included the theater to increase the size of the hotel. The theater's main entrance and box office are at 210 West 46th Street. The box office is at ground level, and there are escalators leading from the ground floor to the auditorium. Due to a lack of space, the wings on each side of the proscenium arch are smaller than mandated by city building codes.
