Garw Valley ({{langx|cy|Cwm Garw}}) is a community and coterminous electoral ward in the north of Bridgend County Borough, South Wales. As the name suggests, it follows and encompasses the valley of the River Garw. The community includes the village of Blaengarw at the head of the valley, followed by Pontycymer and Llangeinor on the river, with Bettws between the Garw and the Llynfi in the south.{{cite web|url=https://www.ordnancesurvey.co.uk/election-maps/gb/ |title=Election maps |publisher=Ordnance Survey|access-date=12 April 2019 }} Garw Valley is bordered to the west by Maesteg, Llangynwyd Middle and Llangynwyd Lower; to the east by Ogmore Valley and to the south by Ynysawdre and St Bride's Minor.

Attractions include the Garw Valley Railway, a four and half mile narrow gauge steam railway, which volunteers began re-laying in 2016. Regular passenger rail services had previously ceased in the valley in 1953, though occasional "enthusiasts' trains" used the line in 1996 and 1997.{{cite book|last=Quick|first=M E|title=Railway passenger stations in England, Scotland and Wales - a chronology|year=2002|publisher=Railway and Canal Historical Society|location=Richmond|page=346|oclc=931112387}}{{cite web|url=https://www.garwvalleyrailway.co.uk/history|title=History Garwvalleyrailway|work=Garw Valley Railway|access-date=13 October 2021}}
