Oz was an independently-published, alternative/underground magazine associated with the international counterculture of the 1960s. While it was first published in Sydney in 1963, a parallel version of Oz was published in London from 1967. The Australian magazine was published until 1969 and the British version until 1973.

The central editor, throughout the magazine’s life in both countries, was Richard Neville. Co-editors of the Sydney version were Richard Walsh and Martin Sharp. Co-editors of the London version were Jim Anderson and, later, Felix Dennis, and then Roger Hutchinson.

The all-graphic ‘Magic Theatre’ edition (OZ No.16, November 1968), overseen by Sharp and (filmmaker Philippe) Mora, has been described by British author Jonathon Green as arguably the greatest achievement of the entire British underground press.
