The 1959 Tasmanian state election was held on 2 May 1959 in the Australian state of Tasmania to elect 35 members of the Tasmanian House of Assembly. The number of members were increased from this election from 30 to 35. The election used the Hare-Clark proportional representation system — seven members were elected from each of five electorates. The two previous elections had resulted in a parliamentary deadlock due to an even number of seats (30) in the House of Assembly. Prior to the 1959 election, the number of seats was increased to 35.
