List of parliamentary constituencies in Northern Ireland
Northern Ireland is divided into 18 Parliamentary constituencies: 4 borough constituencies in Belfast and 14 county constituencies elsewhere. Section 33 of the Northern Ireland Act 1998 provides that the constituencies for the Northern Ireland Assembly are the same as the constituencies that are used for the United Kingdom Parliament. Parliamentary constituencies are not used for local government, which is instead carried out by 11 district councils; these often have different boundaries.
Each constituency returns one Member of Parliament (MP) to the House of Commons at Westminster and five Members of the Legislative Assembly (MLAs) to the devolved Northern Ireland Assembly at Stormont. Six MLAs were returned per constituency until the Assembly Members (Reduction of Numbers) Act (Northern Ireland) 2016 reduced the number to five, effective from the 2017 Assembly election.

Historical representation by party
Where a cell is marked → (with a different colour of frame to the preceding cell) it indicates that the previous MP continued to sit under a new party affiliation. Changes are dated in the header row: either a general election (four-figure year, bold, link) or by-election or change in affiliation (two-figure year, italic, link or details appear on hover).
1801 to 1832 (22 MPs)
* Sir George Hill, 2nd Baronet, was elected to sit as MP for both Coleraine and Londonderry City in the 1806 general election and chose to continue to sit for Londonderry City, hence the 1807 by-election, in which Walter Jones was restored to his seat.
* Charles Brownlow was initially elected as a Tory but at some point changed his affiliation to sit with the Whigs.

* The Parliaments of England by Henry Stooks Smith suggests that after the 1806 election there was a petition, which led to Edward Southwell Ruthven (Whig) being unseated and John Wilson Croker (Tory) being declared duly elected. Parliamentary Election Results in Ireland, 1801–1922, edited by BM Walker, does not make any reference to such a petition.

- The constituency was won by Philip Clarke of Sinn Féin, but he was unseated on petition on the basis that his criminal conviction (for Irish Republican Army activity) made him ineligible. Instead, the seat was awarded to the Ulster Unionist Party (UUP) candidate.
- The seat was originally won by Tom Mitchell of Sinn Féin, but Mitchell was subsequently unseated upon petition, on the grounds that his terrorist convictions made him ineligible to sit in Parliament. The seat was awarded to Charles Beattie of the UUP. However, Beattie in turn was also found ineligible to sit due to holding an office of profit under the crown, triggering a further by-election.
- Original winner of the 1950 election in that seat, James Godfrey MacManaway (UUP), disqualified due to being a clergyman. Teevan won the subsequent by-election

In September 2016 as part of the Sixth Periodic Review of Westminster constituencies, the Boundary Commission for Northern Ireland provisionally proposed a new set of boundaries for a 17-constituency Northern Ireland:
Following two public consultation periods, a set of revised proposals was published on 20 January 2018. Belfast was restored to four seats, and changes elsewhere were scaled back:
Following a final consultation period, the Commission is due to submit a final report to the Secretary of State by 1 October 2018.
