The 2nd government of Ireland was the government of Ireland formed after the 1938 general election to the 10th Dáil held on 17 June. It was a single-party Fianna Fáil government led by Éamon de Valera as Taoiseach. Fianna Fáil had been in office since the 1932 general election. It lasted for 1,828 days.

The 1938 Irish general election to the 10th Dáil was held on Friday, 17 June following the dissolution of the 9th Dáil on 27 May 1938 by the Presidential Commission on the request of Taoiseach Éamon de Valera. It was a snap election, less than a year after the previous election, the proximate cause being the government's loss of an opposition motion recommending use of arbitration to resolve Civil Service labour disputes. The general election took place in 34 parliamentary constituencies throughout Ireland for 138 seats in Dáil Éireann. It was the first election held after the coming into force of the Constitution of Ireland on 29 December 1937. Fianna Fáil won the first overall majority in the history of the State.
