Members of the Western Australian Legislative Council, 1940–1944

This is a list of members of the Western Australian Legislative Council from 22 May 1940 to 21 May 1944. The chamber had 30 seats made up of ten provinces each electing three members, on a system of rotation whereby one-third of the members would retire at each biennial election.

On 16 January 1942, the Governor assented to the Legislative Council (Postponement of Election) Act 1941 (No. 50 of 1941), which extended the terms of all Councillors whose terms expired on 21 May 1942. This was done, in the words of the Act's preamble, due to the "pressing national emergency arising out of the war with Japan in which the Commonwealth of Australia is presently engaged". Later amendments fixed the date as 21 May 1944, and extended all other Councillors' terms by two years.
