Belfast West is a parliamentary constituency in the House of Commons of the United Kingdom.

1950-1974: The County Borough of Belfast wards of Court, Falls, St Anne's, St George's, Smithfield, and Woodvale.

1974-1983: The County Borough of Belfast wards of Court, Falls, St Anne's, St George's, Smithfield, and Woodvale, and the Rural District of Lisburn electoral divisions of Andersonstown, Ballygammon, and Ladybrook.

1983-1997: The District of Belfast wards of Andersonstown, Ballygomartin, Central, Clonard, Court, Falls, Grosvenor, Highfield, Ladybrook, Milltown, North Howard, St James, Suffolk, and Whiterock.

1997-2010: The District of Belfast wards of Andersonstown, Beechmount, Clonard, Falls, Falls Park, Glencairn, Glencolin, Glen Road, Highfield, Ladybrook, Shankill, Upper Springfield, and Whiterock, and the District of Lisburn wards of Collin Glen, Kilwee, Poleglass, and Twinbrook.

2010-present: The District of Belfast wards of Andersonstown, Beechmount, Clonard, Falls, Falls Park, Glencairn, Glencolin, Glen Road, Highfield, Ladybrook, Shankill, Upper Springfield, and Whiterock, and the City of Lisburn wards of Collin Glen, Dunmurry, Kilwee, Poleglass, Twinbrook, and part of Derryaghy.

The seat was restored in 1922 (having been abolished for the 1918 general election) when as part of the establishment of the devolved Stormont Parliament for Northern Ireland, the number of MPs in the Westminster Parliament was drastically cut. In 1983 the Sandy Row and Donegall Road areas were removed leaving a seat centred on the west section of Belfast, though between 1983 and 1997 it included the area around the Docks on the north east side of the Lagan Estuary. Belfast West also contains part of the city of Lisburn district in the shape of the Poleglass and Twinbrook estates.

Prior to the 2010 general election, boundary changes added the Dunmurry ward and the northern part of Derriaghy ward to this seat. Following public consultation, the proposals were passed through Parliament via the Northern Ireland Parliamentary Constituencies Order. In an unprecedented move by a Boundary Commission, an electoral ward was split between constituencies following disquiet in parts of Derriaghy. This ward is now split between Belfast West and Lagan Valley.
