1938 Queensland state election

32 Assembly seats were needed for a majority (0.20 pp)

Elections were held in the Australian state of Queensland on 2 April 1938 to elect the 62 members of the state's Legislative Assembly. The Labor government of Premier William Forgan Smith was seeking a third term in office. During the previous term, the Country and United Australia parties had emerged from the united Country and Progressive National Party, which had represented conservative forces for over a decade.

The most notable feature of the election campaign was the Protestant Labor Party, established in 1937, which claimed that the Forgan Smith Ministry was disproportionately Catholic and made extravagant claims that three-quarters of all police and public servants in the State were Catholic. Despite the campaign, Labor only lost one seat, Kelvin Grove, to the party.

The unsuccessful Protestant Labor candidate for Ithaca, George Webb, lodged a petition against the return of Labor member Ned Hanlon. He was initially successful in the Supreme Court when the case was heard by Justice E.A. Douglas, who voided the election result on 12 October on the basis of a finding that two men who had acted improperly were Hanlon's agents, but Hanlon appealed to the Full Bench of the Supreme Court and on 16 December 1938, his appeal was allowed. A further appeal by Webb to the High Court was refused leave on 31 March 1939.
