South Wales West () was an electoral region of the Senedd, consisting of seven constituencies. The region elected 11 members, seven directly elected constituency members and four additional members. The electoral region was first used in 1999, when the National Assembly for Wales was created.

Each constituency elected one Member of the Senedd by the first past the post electoral system, and the region as a whole elected four additional or top-up Members of the Senedd, to create a degree of proportional representation. The additional member seats were allocated from closed lists by the D'Hondt method, with constituency results being taken into account in the allocation.

County boundaries

The region covered the whole of the preserved county of West Glamorgan, part of the preserved county of Mid Glamorgan and part of the preserved county of South Glamorgan. The rest of Mid Glamorgan was divided between the South Wales Central and South Wales East electoral regions. The rest of South Glamorgan was within the South Wales Central region.

Electoral region profile The region was predominantly urban, taking in Wales' second-largest city, Swansea, as well as working-class towns such as Neath and Port Talbot. However, there were also rural regions, such as on the Gower peninsula. A higher proportion of the local populace were Welsh speakers than in the neighbouring region, South Wales Central.

Constituencies The seven constituencies had the names and boundaries of constituencies of the House of Commons of the Parliament of the United Kingdom (Westminster):
