Elections were held in the state of Western Australia on 15 February 1936 to elect all 50 members to the Legislative Assembly. The Labor Party, led by Premier Philip Collier, won a second term in office against the Country and Nationalist parties, led by Opposition Leader Charles Latham and Norbert Keenan respectively.
No sitting MLA's retired at this election. This was one of the few elections in which the Labor party allowed more than one candidate to run against a sitting MP, namely in the seat of Kalgoorlie. James Cunningham was defeated by fellow Labor candidate Herbert Styants, and Cunningham transferred to the Australian Senate the following year.
At the election, 5 sitting members (four Labor and one Nationalist) were defeated—three of them by independents. In Maylands, one-term MLA Robert Clothier (Labor) was defeated by independent Nationalist Harry Shearn, who won with preferences from two endorsed nationalists. In East Perth, Minister for Employment and Labour James Kenneally was defeated by former Labor member Thomas Hughes, and the Nationalist member for Nelson, John Henry Smith, was defeated by independent Clarence Doust. The remaining seats, Subiaco and Albany, were lost by Labor to the Nationalist and Country parties respectively.
