Selina Sarah Elizabeth Siggins was an Australian political activist who became the first woman to stand for the Australian House of Representatives. She ran as an independent at the 1903 federal election, the first at which women were eligible to be candidates. Although she spent most of her life in New South Wales, in 1918 she also became one of the first two women to stand for the Parliament of South Australia. Siggins was introduced to politics through her involvement in the labour movement, and initially supported the Labor Party. She eventually fell out with the party over its refusal to endorse her as a candidate. Her final run for parliament came at the 1922 federal election, where she became the first woman to stand for the Country Party.

The 1903 Australian federal election was held in Australia on 16 December 1903. All 75 seats in the House of Representatives, and 19 of the 36 seats in the Senate were up for election. The incumbent Protectionist Party minority government led by Prime Minister Alfred Deakin retained the most House of Representatives seats of the three parties and retained government with the parliamentary support of the Labour Party led by Chris Watson. The Free Trade Party led by George Reid remained in opposition.
