The Rialto Theatre was a movie palace in New York City located at 1481 Broadway, at the northwest corner of Seventh Avenue and 42nd Street, within the Theater District of Manhattan. The 1,960-seat theater opened on April 21, 1916, on the former site of Oscar Hammerstein's Vaudeville venue the Victoria Theatre. Together with Strand Theatre, they were the most important movie theatres on Broadway at the time. It exclusively played Triangle Film Corporation films but beginning in 1919, the Rialto Theatre premiered many releases by Paramount Pictures (then known as the Famous Players-Lasky Corporation) until being supplanted by the newly built Paramount Theatre in 1926 as the movie studio's flagship theater in New York City.
