The Northern Ireland House of Commons existed from 1921 to 1973 as the lower House of the devolved legislature of the part of the United Kingdom called Northern Ireland.

In 1921–29 the 52 provincial Members of Parliament were elected using proportional representation by the single transferable vote in multi member constituencies. The constituencies which returned one or two members to the UK Parliament, between 1922 and 1950, were used for Northern Ireland devolved elections in the 1921–29 period.

Between 1929 and 1969 there were 48 single member constituencies, using the first past the post method of election. The non-territorial University constituency continued to return 4 members using the single transferable vote.

For the 1969 election 4 new territorial constituencies were created to replace the University seats. The 52 constituencies ceased to exist after the Parliament of Northern Ireland was suspended in 1972 and abolished in 1973.

The legislatures of the United Kingdom are derived from a number of different sources.

The United Kingdom, a sovereign state to the northwest of continental Europe, consists of England, Northern Ireland, Scotland and Wales.

Consequently, there is "no common stratum of administrative unit encompassing the United Kingdom".

The Northern Ireland Assembly, often referred to by the metonym Stormont, is the devolved legislature of Northern Ireland. It has power to legislate in a wide range of areas that are not explicitly reserved to the Parliament of the United Kingdom, and to appoint the Northern Ireland Executive. It sits at Parliament Buildings at Stormont in Belfast.

These same constituencies also replaced those provided in the Redistribution of Seats (Ireland) Act 1918 for representation of Ireland in the House of Commons of the United Kingdom at Westminster. Sinn Féin used these constituencies to elect the Second Dáil (1921–22) and those constituencies in Southern Ireland were used to elect the Third Dáil (1922–23).
