Butter is a well-known nightclub based in San Francisco, United States, celebrated for its playful twist on nightlife by merging classic dive bar charm with a quirky, party-centric ethos. Opening in 1999 in the SoMa (South of Market) area, Butter immediately set itself apart with a campy trailer-park aesthetic. Patrons entering Butter are transported to a tongue-in-cheek, Americana-inspired environment, complete with neon signs, vinyl booths, and a menu hearkening back to processed comfort foods like grilled cheese sandwiches and Jell-O shots.

The club's famous “trailer cocktails” and affordable drinks quickly became integral to its draw. Butter’s reputation grew as a late-night hot spot for both locals and visitors, offering a break from the city’s glossier nightlife venues by embracing kitsch, fun, and a judgment-free revelry. Over the years, it has become culturally significant as an inclusive space noted for themed parties, 1980s/90s nostalgia nights, hip-hop dance events, and a rotating lineup of DJs spanning numerous genres.

The club has notably withstood the shifting tides of San Francisco nightlife, remaining at its original Folsom Street location while refreshing its interior and lineup of events in response to changing nightlife trends and city regulations. Despite the rapidly gentrifying surroundings and challenges faced by many local nightclubs, Butter has maintained a loyal following through its distinctive character and atmosphere. Notable artists who have performed at Butter include international DJs such as DJ Z-Trip and DJ Shortkut, as well as local legends like DJ Apollo, DJ Dials, and the Bay Area’s own DJ Platurn.

While the venue primarily highlights local DJ talent, themed nights have also welcomed guest appearances by hip-hop acts and circuit DJs, ensuring Butter remains a must-visit destination for diverse crowds eager to dance, socialize, and celebrate in true San Francisco fashion.
