The London Fog was a 1960s nightclub located on the Sunset Strip in what was then unincorporated Los Angeles County, California (now in the city of West Hollywood).

It is most notable for being the venue where The Doors had their first regular gigs for several months in early 1966 before becoming the house band at the nearby Whisky a Go Go.

Both Duke's Coffee Shop and Sneaky Pete's, a former nightclub featuring music, claimed to have replaced the London Fog, but this is not true.

In Oliver Stone's 1991 film The Doors, the scenes depicting the London Fog were shot at the location that became the Viper Room in 1993.

In the Tarantino Universe, London Fog is still open in 1969, as mentioned by actor/director Sam Wanamaker (played by Nicholas Hammond) in the film Once Upon a Time in Hollywood.
