Folsom Street Fair (FSF) is an annual BDSM and leather subculture street fair, held in September that concludes San Francisco's "Leather Pride Week". The Folsom Street Fair, sometimes referred to simply as "Folsom", takes place on the last Sunday in September, on Folsom Street between 8th and 13th Streets, in San Francisco's South of Market district. The event started in 1984, and is California's third-largest single-day, outdoor spectator event and the world's largest leather event and showcase for BDSM products and culture. It has grown as a non-profit charity, and local and national non-profits benefit with all donations at the gates going to charity groups as well as numerous fundraising schemes within the festival including games, beverage booths and even spanking for donations to capitalize on the adult-themed exhibitionism. Origin of the leather subculture Although sadomasochism has been practiced for many centuries, the modern gay leather scene in the United States developed beginning in 1945 when thousands of gay servicemen were given blue discharges from service after World War II and came to the major port cities of the United States to live in gay ghettos. In 1953, the Marlon Brando film The Wild One appeared, and some butch gays began to imitate Brando by wearing black leather jackets, a black leather cap, black leather boots and jeans and, if they could afford it, by also riding motorcycles. In the 1950s, the magazine Bizarre familiarized people with sexual fetishism.

Folsom Street has been the center of San Francisco's men's leather community since the mid-1960s. Before centering in the South of Market neighborhood, leather friendly bars were located in the Embarcadero (Jack's On The Waterfront at 111 Embarcadero 1952–1963, On The Levee ?–1972), and the Tenderloin (The Spur Club at 126 Turk – raided and closed in 1959, The Why Not at 518 Ellis – opened and closed in 1960, The Hideaway at 438 Eddy – raided and closed in 1961). The first leather bar in SOMA was the Tool Box, a gay leather bar which opened in 1961 at 339 4th St and closed in 1971.
