Clay Theatre is a historic 1913 single screen theater building in the Pacific Heights neighborhood of San Francisco, California, United States.

[2] It was founded in c. 1913 – c. 1914, as The Regent, a nickelodeon-style small movie theater often showing Mary Pickford films.

[5] In the 1950s, the building exterior was greatly modified, including moving of the ticketing booth and a change to the shape of the entrance (formerly an archway).

[1] Filmmaker John Waters had remembered early showings of Pink Flamingos (1972) at the Clay Theatre.

[9] The local community rallied in hopes of the building re-opening as a movie theater,[1] and in May 2022 it was designated a city landmark.
