This is a list of members of the Australian Senate from 1935 to 1938. Half of its members were elected at the 19 December 1931 election and had terms starting on 1 July 1932 and finishing on 30 June 1938; the other half were elected at the 15 September 1934 election and had terms starting on 1 July 1935 and finishing on 30 June 1941. The process for filling casual vacancies was complex. While senators were elected for a six-year term, people appointed to a casual vacancy only held office until the earlier of the next election for the House of Representatives or the Senate.
