Simon Findlay Crean (26 February 1949 – 25 June 2023) was an Australian politician and trade unionist. He was the leader of the Australian Labor Party (ALP) and leader of the opposition from 2001 to 2003. He represented the seat of Hotham in the House of Representatives from 1990 to 2013 and was a cabinet minister in the Hawke, Keating, Rudd and Gillard governments.
Crean was born in Melbourne, the son of Frank Crean who was deputy prime minister under Gough Whitlam. He studied law and economics at Monash University and was involved in the trade union movement from a young age, becoming general secretary of the Storemen and Packers' Union in 1979. He was elected vice-president of the Australian Council of Trade Unions (ACTU) in 1981 and president in 1985. Crean stood down from this role upon his election to parliament at the 1990 federal election, and was immediately appointed Minister for Science and Technology in the Hawke government. He held several other ministerial posts until Labor's defeat at the 1996 election.
