|Council:||Rhondda Cynon Taf|
Gilfach Goch is a small former coal mining village in Glamorgan, near the larger community of Tonyrefail. It is situated in the Little Ogmore Valley between the Large Ogmore Valley to the west and the Rhondda Valley to the east.
The author Richard Llewellyn stayed in Gilfach Goch (1939) for the writing of his novel 'How Green Was My Valley' that is set in a fictional mining village based on Gilfach Goch. Llewellyn would spend long summer holidays with his grandfather in the village.
The oldest building in the village is the Griffin Inn, a public house which is situated in low marshy ground at the bottom of a country lane.
