State elections were held in South Australia on 5 April 1930. All 46 seats in the South Australian House of Assembly were up for election. The incumbent Liberal Federation government led by Premier of South Australia Richard L. Butler was defeated by the opposition Australian Labor Party led by Leader of the Opposition Lionel Hill.
Each district elected multiple members. This election saw the change from first past the post (plurality) to instant-runoff (preferential) voting, which also meant that electors cast a single vote rather than multiple votes. With 30 of 46 seats in the House of Assembly, the election remained South Australian Labor's biggest seat win until the record was exceeded in 2026.
