Results of the 1938 South Australian state election (House of Assembly)

The 1938 South Australian state election, held on March 19, 1938, determined the composition of the House of Assembly, the lower house of the Parliament of South Australia. The election saw the incumbent Liberal and Country League (LCL), led by Premier Richard L. Butler, defeated by the Australian Labor Party (ALP), led by Robert Richards.

The election was conducted using a preferential voting system in single-member constituencies. A total of 39 seats were contested.

The Labor Party won a narrow majority of seats, securing 20 seats to the LCL's 16. The Country Party, a minor party representing rural interests, won 3 seats. This result marked the end of the LCL's long period of dominance in South Australian politics.

Robert Richards subsequently became Premier, forming a Labor government. However, Richards's tenure was short-lived; he was defeated in a no-confidence motion in 1939, leading to the formation of a minority LCL government under Thomas Playford IV.

Key figures in the election included Richard L. Butler (LCL Premier), Robert Richards (ALP Leader), and Thomas Playford IV (LCL). The election was notable for its relatively close result and for ending the LCL's premiership. The results reflected growing public dissatisfaction with the Butler government and a shift in voter sentiment towards the Labor Party.
