The Bag O'Nails was a live music club and meeting place for musicians in the 1960s and situated at 9, Kingly Street, Soho, London, England. It had formerly been known as the Pinstripe Club, where John Profumo was first introduced to Christine Keeler, a meeting which led to the Profumo affair.

Bands and other musicians who played and socialised there included Georgie Fame, Jimi Hendrix, Bobby Tench, The Gass and Eric Burdon. The venue also hosted an early gig (possibly the first) by the Jimi Hendrix Experience. Other performers who frequented the venue including Tom Jones, The Who and The Animals. Paul McCartney met his future wife Linda Eastman here in 1967.
