The 1974 Australian federal election was held in Australia on 18 May 1974. All 127 seats in the House of Representatives and all 60 seats in the Senate were up for election, due to a double dissolution. The incumbent Labor Party led by Prime Minister Gough Whitlam defeated the opposition Liberal–Country coalition led by Billy Snedden. This marked the first time that a Labor leader won two consecutive elections.

The House of Representatives is the lower house of the bicameral Parliament of Australia, the upper house being the Senate. Its composition and powers are set down in Chapter I of the Constitution of Australia.
