Sir George Russell Drysdale, also known as Tass Drysdale, was an Australian artist. He won the prestigious Wynne Prize for Sofala in 1947, and represented Australia at the Venice Biennale in 1954. He was influenced by abstract and surrealist art, and "created a new vision of the Australian scene as revolutionary and influential as that of Tom Roberts".

The Wynne Prize is an Australian landscape painting or figure sculpture art prize. As one of Australia's longest-running art prizes, it was established in 1897 from the bequest of Richard Wynne. Now held concurrently with the Sir John Sulman Prize and the Archibald Prize at the Art Gallery of New South Wales in Sydney.
