Sir Richard Butler (3 December 1850 – 28 April 1925) was an Australian politician and Premier of South Australia.
Butler was born at Stadhampton, near Oxford, England, elder son of Richard Butler, pastoralist, and his wife Mary Eliza, née Sadler. The family emigrated to South Australia, arriving in Adelaide on 8 March 1854. Butler was educated at St Peter's College, Adelaide, then spent many years as a farmer and grazier. He was a Justice of the Peace before he was 30.
Butler attempted to enter parliament early in 1890 when he stood for Yatala but was defeated. A few months later he won the seat at a by-election. On 13 April 1898 he succeeded Cockburn as minister of agriculture in the Kingston ministry which resigned in December 1899.
