Cromac, a division of Belfast, was a UK parliamentary constituency in Ireland.
It returned one Member of Parliament (MP) to the House of Commons of the United Kingdom from 1918 to 1922, using the first past the post electoral system.
The constituency was created by the Redistribution of Seats (Ireland) Act 1918 and comprised the western half of South Belfast, and contained the then-Cromac and Windsor wards of Belfast Corporation.
[1] Prior to the 1918 general election and after the dissolution of Parliament in 1922 the area was part of the Belfast South constituency.
[citation needed] The constituency was a predominantly Unionist area, with some Labour support.
