The 1925 Northern Ireland general election was held on 3 April 1925. It was the second election to the Parliament of Northern Ireland. It saw significant losses for the Ulster Unionist Party, although they maintained their large majority. This was the last election for the Stormont parliament conducted using Single transferable voting, a form of Proportional Representation. Fifty-two members were elected in ten districts, which each elected between four and eight members. The Ulster Unionist government abolished proportional representation during this parliament and replaced it with the first-past-the-post system used in Great Britain.

The Parliament of Northern Ireland was the home rule legislature of Northern Ireland, created under the Government of Ireland Act 1920, which sat from 7 June 1921 to 30 March 1972, when it was suspended because of its inability to restore order during The Troubles, resulting in the introduction of Direct Rule. It was abolished under the Northern Ireland Constitution Act 1973.
