Porthcawl ( ) is a town and community in the Bridgend County Borough of Wales. It is on the south coast of Wales, 25 miles (40 km) west of Cardiff and 19 miles (31 km) southeast of Swansea.

South Wales is a loosely defined region of Wales bordered by England to the east and mid Wales to the north. Generally considered to include the historic counties of Glamorgan and Monmouthshire, south Wales extends westwards to include Carmarthenshire and Pembrokeshire. In the western extent, from Swansea westwards, local people would probably recognise that they lived in both south Wales and west Wales. The Brecon Beacons National Park covers about a third of south Wales, containing Pen y Fan, the highest British mountain south of Cadair Idris in Snowdonia.
