The Third Amendment of the Constitution Bill 1958 was a proposal to amend the Constitution of Ireland to alter the electoral system from proportional representation under the single transferable vote (PR-STV) to first-past-the-post (FPTP). The proposal was rejected in a referendum held on 17 June 1959. This was the same date as the presidential election in which Taoiseach Éamon de Valera was elected as president.
