The 1909 Tasmanian state election was held on Friday, 30 April 1909 in the Australian state of Tasmania to elect 30 members of the Tasmanian House of Assembly. At the 1909 election there was a reduction in the number of members from 35 to 30 and the first statewide use of the Hare-Clark proportional representation system — six members were elected from each of five electorates. The election saw an increase in Labour seats from 7 to 12, at the expense of the Anti-Socialist Party.
