The Circle in the Square Theatre is a Broadway theater at 235 West 50th Street, within the basement of Paramount Plaza, in the Midtown Manhattan neighborhood of New York City. The current Broadway theater, completed in 1972, is the successor of an off-Broadway theater of the same name, co-founded around 1950 by a group that included Theodore Mann and José Quintero. The Broadway venue was designed by Allen Sayles; it originally contained 650 seats and uses a thrust stage that extends into the audience on three sides. The theater had 751 seats as of 2022.
