South Antrim is a parliamentary constituency in the United Kingdom House of Commons represented since 2015 by Danny Kinahan of the Ulster Unionist Party.

From 1885, this constituency was one of four county divisions of the former Antrim constituency. It comprised the baronies of Massereene Upper, Massereene Lower, and Antrim Upper, and parts of the Baronies of Upper Toome and Belfast Upper, and so much of the Parliamentary Borough of Belfast as was in the County of Antrim.

It returned one Member of Parliament. In 1922, it was merged into a new Antrim constituency.

The seat was re-created in 1950 when the old Antrim two MP constituency was abolished as part of the final move to single member seats. The seat was reduced in size for the 1974 general election, with the town of Carrickfergus and the areas between it and Larne town transferred to North Antrim. Additionally some territory was transferred to Belfast West. Despite these changes, the seat had become the largest in the entire United Kingdom by the time of the Northern Ireland Assembly elections of 1982, by which time its electorate had passed the 131,000 mark. For the 1983 general election Northern Ireland received new seats. Consequently, South Antrim was significantly reduced, losing a lot of territory to the new seats of East Antrim and Lagan Valley as well as minor sections to Belfast West, Belfast North and Upper Bann. The new South Antrim which was fought for the 1983 election contained only 43% of the previous seat. In 1995 there were minor changes around the borders with North Belfast and West Belfast. The seat fought at the 2005 election encompassed the entirety of the district of Antrim and part of the district of Newtownabbey.
