Garw Valley (Welsh: Cwm Garw) is a community and coterminous electoral ward in the north of Bridgend County Borough, South Wales.

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.

[2] 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.

Regular passenger rail services had previously ceased in the valley in 1953, though occasional "enthusiasts' trains" used the line in 1996 and 1997.

[3][4] At the local level, Garw Valley elects 13 community councillors to Garw Valley Community Council, from the four wards of Bettws, Llangeinor, Pontycymmer and Blaengarw.
