The Bijou Theatre is a theater located in Knoxville, Tennessee, United States. Built in 1909 as an addition to the Lamar House Hotel, the theater has at various times served as performance venue for traditional theatre, vaudeville, a second-run moviehouse, a commencement stage for the city's African-American high school, and a pornographic movie theater. The Lamar House Hotel, in which the theater was constructed, was originally built in 1817, and modified in the 1850s. The building and theater were added to the National Register of Historic Places in 1975.
