The 1990 Australian federal election was held in Australia on 24 March 1990. All 148 seats in the House of Representatives and 40 seats in the 76-member Senate were up for election. The incumbent Australian Labor Party, led by Bob Hawke, defeated the opposition Liberal Party of Australia, led by Andrew Peacock, with its coalition partner, the National Party of Australia, led by Charles Blunt, despite losing the nationwide popular and two-party-preferred vote. The result saw the re-election of the Hawke government for a fourth successive term.
