The 1919 Tasmanian state election was held on 31 May 1919 in the Australian state of Tasmania to elect 30 members of the Tasmanian House of Assembly. The election used the Hare-Clark proportional representation system — six members were elected from each of five electorates. By the 1919 election, the Liberal Party had regrouped and been renamed as the Nationalist Party. The Premier of Tasmania, Walter Lee, had led the party for a relatively untroubled three years, despite the Liberals' one-seat majority over Labor and the uncertainty of World War I.
