The National Theater was a Yiddish theater at the southwest corner of Second Avenue (Chrystie) and Houston Street in Manhattan, New York City, United States. When first built it was leased to Boris Thomashefsky and Julius Adler. The theater was one of the many designed by architect Thomas W. Lamb, and seated 1900 when it was opened on 6 May 1913. It was built as one of a pair of theaters, with the Crown Theater, seating 963, on the upper level. Both theaters closed in 1941, re-opened in 1951 as a pair of Cinemas (the National Theater and the Roosevelt Theater), and were demolished in 1959.
