John Barry Humphries, AO, CBE (17 February 1934 - 22 April 2023) was an Australian comedian, satirist, dadaist, artist, author and character actor, perhaps best known for his on-stage and television alter egos Dame Edna Everage, a Melbourne housewife and "gigastar", and Sir Les Patterson, Australia's foul-mouthed cultural attaché to the Court of St. James's.

He was a film producer and script writer, a star of London's West End musical theatre, an award-winning writer and an accomplished landscape painter. For his delivery of dadaist and absurdist humour to millions, biographer Anne Pender described Humphries in 2010 as not only the most significant theatrical figure of our time … [but] the most significant comedian to emerge since Charlie Chaplin. Humphries' characters, especially Dame Edna Everage, have brought him international renown, and he had appeared in numerous films, stage productions and television shows. Originally conceived as a dowdy Moonee Ponds housewife who caricatured Australian suburban complacency and insularity, Edna had evolved over four decades to become a satire of stardom, the gaudily dressed, acid-tongued, egomaniacal, internationally feted Housewife Gigastar, Dame Edna Everage. Humphries' other major satirical character creation was the archetypal Australian bloke Barry McKenzie, who originated as the hero of a comic strip about Australians in London (with drawings by Nicholas Garland) which was first published in Private Eye magazine.
