Crawford Vaughan, Australian politician, 27th Premier of South Australia (d. 1947)
Crawford Vaughan (14 July 1874 – 15 December 1947) was an Australian politician, and the Premier of South Australia from 1915 to 1917. He was a member of the South Australian House of Assembly from 1905 to 1918, representing Torrens (1905–1915) and Sturt (1915–1918). Elected for the United Labor Party, he served as Treasurer in the Verran government, succeeded Verran as Labor leader in 1913, and was elected Premier after the Labor victory at the 1915 state election.

Vaughan's career was curtailed by the 1916–17 Labor split over conscription in World War I, as Vaughan and other supporters of conscription were expelled from the Labor Party in early 1917. Vaughan continued in office until July heading a minority government of the splinter National Party; however, his government was then ousted by the conservative Liberal Union opposition of Archibald Peake. The National Party went into coalition, serving under Peake as junior instead of senior partner, but Vaughan did not take a ministerial portfolio, spent most of his remaining term overseas, and was defeated at the 1918 election after launching a last-minute campaign as an independent candidate.
