The 1943 Irish general election to the 11th Dáil was held on Wednesday, 23 June, having been called on 31 May by proclamation of President Douglas Hyde on the advice of Taoiseach Éamon de Valera. It took place in 34 parliamentary constituencies for 138 seats in Dáil Éireann, the house of representatives of the Oireachtas. Fianna Fáil lost its overall majority of seats. The outgoing 10th Dáil was dissolved on 26 June, although it had not met after 26 May.

The Taoiseach is the head of government or prime minister of Ireland. The office is appointed by the President of Ireland upon the nomination of Dáil Éireann and the office-holder must retain the support of a majority in the Dáil to remain in office.
