Indica Gallery was a counterculture art gallery in Mason's Yard (off Duke Street), Mayfair, London, England during the late 1960s, in the basement of the Indica Bookshop co-owned by John Dunbar, Peter Asher and Barry Miles. It was supported by Paul McCartney and hosted a show of Yoko Ono's work in November 1966 at which Ono first met John Lennon.
Today it is the site of James Hyman Fine Art, one of the leading London specialists in Twentieth Century British art.
