The prime minister of Northern Ireland was the head of the Government of Northern Ireland between 1921 and 1972. No such office was provided for in the Government of Ireland Act 1920; however, the Lord Lieutenant of Ireland, as with governors-general in other Westminster Systems such as in Canada, chose to appoint someone to head the executive even though no such post existed in statute law. The office-holder assumed the title prime minister to draw parallels with the prime minister of the United Kingdom. On the advice of the new prime minister, the lord lieutenant then created the Department of the Prime Minister. The office of Prime Minister of Northern Ireland was suspended in 1972 and then abolished in 1973, along with the contemporary government, when direct rule of Northern Ireland was transferred to London.

It was abolished under the Northern Ireland Constitution Act 1973.

Two Ministers of Finance went on to be Prime Minister, while two more, Maginness and Jack Andrews were widely seen as possible successors to the Premiership.

The Civil Authorities Act 1922, often referred to simply as the Special Powers Act and known as the "Flogging Act", was an act passed by the Parliament of Northern Ireland during the partition of Ireland and shortly after the establishment of Northern Ireland. The Act was renewed annually and in 1928 was renewed for five years and made permanent in 1933 and not repealed until 1973. Its sweeping powers made it highly controversial, and it was seen by much of the Irish nationalist community as a tool of Ulster unionist oppression. The Act was eventually repealed by the Northern Ireland Act 1973, following the abolition of Northern Ireland's parliament and the imposition of direct rule by the British government.
