Trebanog is a village in the Cymmer electoral ward lying on the southernmost outskirts of the Rhondda Valley, Rhondda Cynon Taf, Wales, located off the A4233 road between Porth and the town of Tonyrefail.[1] Trebanog is an outlying district of the community of Cymmer, and is neighboured by the settlement of Edmondstown (a district of Penygraig). The area has been described as being on "high ground that seals off the Rhondda from the Vale of Glamorgan".[2] Historically it was a mining village,[3] and was home to the Trebanog Working Men's Club and Institute.[4]
