The 1955 Australian federal election was held in Australia on 10 December 1955. All 122 seats in the House of Representatives and 30 of the 60 seats in the Senate were up for election. An early election was called to bring the House and Senate elections back in line; the previous election in 1954 had been House-only. The incumbent Liberal–Country coalition led by Prime Minister Robert Menzies increased its majority over the opposition Labor Party, led by H. V. Evatt.
Future Prime Minister Malcolm Fraser and future opposition leader Billy Snedden both entered parliament at this election.
Ten members were elected unopposed – five Liberal and five Country. This would be the last federal election where any seat attracted only one candidate.
^The Northern Territory and Australian Capital Territory each had one seat, but members for the territories did not have full voting rights until 1966 and did not count toward government formation.
Prior to 1984 the AEC did not undertake a full distribution of preferences for statistical purposes. The stored ballot papers for the 1983 election were put through this process prior to their destruction. Therefore, the figures from 1983 onwards show the actual result based on full distribution of preferences.
