Alcazar Theatre, Theatre and masonic temple in San Francisco, United States

The Alcazar Theatre is a theater on Geary Street in San Francisco, housed inside a former Masonic temple. The building has a single main stage and seats around 500 people.

The building was constructed in 1917 for the Shriners, a fraternal order tied to Freemasonry, and was designed by architect T. Patterson Ross. Decades later it was converted into a theater and has hosted performances since.

The theatre carries the name of the Alcazar Theatre at 260 O'Farrell Street, which closed on 31 December 1961 and was later demolished; the Geary Street building took over the name when it became a theatre in 1976. Its 1917 exterior imitates the Alhambra, and the June 1917 Architect and Engineer called it "an adaptation from Alhambra". Today it stages touring Broadway and Off Broadway plays, variety, cabaret and comedy.

The theater sits in a part of San Francisco where venues and restaurants are close together, making it easy to combine an evening out. It is worth checking what is on before visiting, as the program changes regularly.

The June 1917 issue of Architect and Engineer likened the new Shriners' temple to the Alhambra, calling it "an adaptation from Alhambra, a building that stands as the highest mark of Arabian art and civilization." The building cost $150,000 and was designed by T. Patterson Ross in Exotic Revival style.
