Frank Gilbert Crichlow (13 July 1932 – 15 September 2010) was a British community activist and civil rights campaigner, who became known in 1960s London as a godfather of black radicalism.
He was a central figure in the Notting Hill Carnival, his restaurant the Mangrove serving for many years as the base from which activists, musicians and artists organised the event, as well as becoming "the symbol of resistance to police persecution".
