California Hall, originally named Das Deutsche Haus[3] (English: The German House, sometimes also referred to in incorrect German as Das Deutsches Haus), is a historic commercial building and event venue built in 1912, located in the Polk Gulch/Tenderloin neighborhood in San Francisco, California.

[7][2] In 1912, when the Das Deutsche Haus was built, Polkstrasse (now Polk Street) was a main commercial shopping center for German immigrants.

[9] In 1918, the building's name was changed to California Hall, as part of what has been described as a general "process of physically removing the presence of German influence" in San Francisco following the entry of the US into World War I on the side opposing Germany.

[13] The 1965 New Years Ball (a fundraiser for the Council on Religion and the Homosexual, and other homophile organizations) was held January 1, 1965 at the California Hall.

[13] During the event, the police interfered with the gay attendees by taking photos of each person entering the building; which prompted a legal battle led by Evander Smith and Herb Donaldson.

[6] In 1965, the venue hosted two productions by Family Dog; The Charlatans with the Ken Kesey and the Merry Pranksters Acid Tests happening (at the same time at The Fillmore, a bus moved between the two music halls).
