John Tonkin Labor Charles Court Liberal/National coalition Elections were held in the state of Western Australia on 30 March 1974 to elect all 51 members to the Legislative Assembly and 15 members to the 30-seat Legislative Council.

The Liberal Party won the election after a campaign focused mostly on inflation, industrial unrest, states' rights and education.

[1] The outgoing Tonkin government had had a turbulent ride in its three years of office, having only a one-seat majority in the Assembly and being outnumbered two-to-one in the Council.

[2] The 15-month-old Whitlam Labor federal government had proven unpopular in Western Australia which saw it as taking a centralist view towards federal-state affairs, and Whitlam himself was hit by a soft drink can and a tomato whilst addressing voters at Forrest Place during the campaign.

The Country Party had tentatively merged with the Democratic Labor Party in the period preceding the election, going to the voters as the National Alliance which put forward a centrist platform—however, they lost both votes and seats as compared to the 1971 election in doing so.
