Millicent was an electoral district of the House of Assembly in the Australian state of South Australia from 1956 to 1977. Based on the town of Millicent, the seat was carved out of the south of the seat of Victoria. It was held by Labor as a marginal to safe seat until the 1975 election with the seat won by the Liberals as a fairly safe seat for one term until it was abolished, with the town of Millicent absorbed back into the seat of Victoria. Its best-known holder was Des Corcoran, who served as Deputy Premier under Don Dunstan.
