The 1981 Irish general election to the 22nd Dáil was held on Thursday, 11 June, following the dissolution of the 21st Dáil on 21 May by President Patrick Hillery on the request of Taoiseach Charles Haughey. The general election took place in 41 Dáil constituencies throughout Ireland for 166 seats in Dáil Éireann, the house of representatives of the Oireachtas. The number of seats in the Dáil was increased by 18 from 148 under the Electoral (Amendment) Act 1980.

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.
