Belfast South was a parliamentary constituency in the United Kingdom House of Commons from 1885 to 1918 and from 1922 to 2024. From the 2024 general election, it was succeeded by the constituency of Belfast South and Mid Down.
History
In the late nineteenth and early twentieth centuries, Belfast South tended to elect 'rebel unionists' such as William Johnston, who defied a ban on Orange marches, and Thomas Sloan, founder of the Independent Orange Order.
Belfast South contained some of Belfast's most expensive residential districts as well as Queen's University Belfast. The overall tenor of the constituency is middle-class – young, trendy and cosmopolitan towards the city centre, with Northern Ireland's biggest concentrations of both students and ethnic minorities, and further out from the city centre it is settled and prosperous. Despite this, significant pockets of inner-city working class areas such as the Markets and a number of isolated suburban estates exist in the constituency.
There had been particularly rapid demographic change in Belfast South from around the year 2000. The 2011 census revealed that Belfast South consisted of a slightly larger Catholic population than Protestant and while the constituency traditionally has had a unionist majority, the nationalist vote surpassed this in more recent elections. There have also been strong votes for other parties such as the Alliance Party of Northern Ireland, Green Party, the Conservatives and the Northern Ireland Women's Coalition. The constituency has witnessed a steady series of candidates backed by groups who aspire to support the British Labour Party despite its prior ban on membership and organisation in Northern Ireland, though their results have been minimal. Until the 1990s the main focus of attention had been on contests between unionist candidates.
In the February 1974 general election the seat was won by Robert Bradford of the Vanguard Unionist Progressive Party on a united anti-Sunningdale Agreement slate with the Ulster Unionist Party and the Democratic Unionist Party. He defeated Rafton Pounder, the sitting Unionist MP who defended his seat as a Pro-Assembly Unionist. Bradford held the seat for the next seven years, though in February 1978 he and the rump of Vanguard reunited with the Ulster Unionists. At the end of 1981 Bradford was assassinated by the IRA in a Belfast community centre while hosting a political surgery.
The subsequent by-election garnered much interest as it was expected that the Democratic Unionist Party would take the seat, building on their steady rise which had seen them gain both Belfast North and Belfast East at the previous general election. However, the DUP came third, behind the Alliance Party of Northern Ireland, and the UUP's candidate Martin Smyth won the seat, holding it until 2005. The by-election was extremely significant at the time in that it was the first at which the DUP tide ebbed.
In January 2005 Smyth announced that he would retire at the 2005 general election, raising speculation both as to whom the Ulster Unionists would field in succession to him and what effect a different candidate would have upon their share of the vote. The UUP selected Assembly member Michael McGimpsey, albeit with a highly controversial and bitter selection. McGimpsey was repudiated by many prominent Unionists, including both Smyth and former UUP leader James Molyneaux. The DUP selected Jimmy Spratt and offered an electoral pact to the UUP that would give each party a free run at one out of South Belfast and Fermanagh and South Tyrone. This offer was rejected by the UUP.
In the event, the DUP and UUP both fielded candidates which split the vote. The nationalist vote mainly went for the SDLP over Sinn Féin, with the result that the SDLP took the seat despite a majority of votes cast for unionist candidates.
In the 2010 general election, Sinn Féin opted not to stand against the SDLP to avoid splitting the nationalist vote. The SDLP won the seat with a majority of 6,000. This was the seat in which the Alliance Party had their second-best showing, polling 15% of the votes. Alasdair McDonnell retained the seat in May 2015, with only 24.5% of the vote, as Sinn Féin opted to stand. This is the smallest proportion of the vote a winning candidate has ever achieved in a UK general election.
In the 2017 general election the seat was won by Emma Little-Pengelly of the DUP with Alasdair McDonnell losing his seat along with all other SDLP MPs in Northern Ireland. This was won back for the SDLP by Claire Hanna in 2019, with Sinn Féin again opting not to stand. This was the first time since 1987 that the winning candidate in the constituency had a majority of the vote.
Boundaries
Under the Redistribution of Seats Act 1885, the parliamentary borough of Belfast was expanded. The 2-seat borough constituency of Belfast in the House of Commons of the United Kingdom was divided into four divisions: East, South, West, and North.
The city boundaries were expanded under the Belfast Corporation Act 1896. Under the Redistribution of Seats (Ireland) Act 1918, the parliamentary borough was extended to include the whole city and the number of divisions increased from 4 to 9. The Cromac and Ormeau divisions largely replaced the South division. These boundaries were in effect at the 1918 general election.
The Government of Ireland Act 1920 established the Parliament of Northern Ireland, which came into operation in 1921. The representation of Northern Ireland in the Parliament of the United Kingdom was reduced from 30 MPs to 13 MPs, taking effect at the 1922 United Kingdom general election. These changes saw a 4-seat Belfast South constituency in the House of Commons of Northern Ireland and Belfast South re-established as a one-seat constituency at Westminster.

Under the 2023 review of Westminster constituencies, the seat was proposed to be replaced by Belfast South and Mid Down. The redrawn constituency contained 90.8% of the population of the former Belfast South. This seat was first contested at the 2024 United Kingdom general election.
Members of Parliament
The Member of Parliament for Belfast South at the time of its abolition was Claire Hanna of the Social Democratic and Labour Party, who defeated Emma Little-Pengelly of the Democratic Unionist Party in the 2019 general election.
