Abercwmboi is a village in the Welsh county borough of Rhondda Cynon Taf in Wales, United Kingdom.
Abercwmboi is one of the last remaining villages in the Cynon Valley. It has retained its identity and not been developed as many other Cynon Valley villages. As a result, is a very close and friendly community. Many families continue to remain within the community and have a great sense of belonging.
Abercwmboi Workmans Hall - which was paid for out of the miners contributions. Many trips and events have been run from here, with the miners taking their families on day trips, as a community. The hall has also been used as a cinema and a public house over the years.
It lies on the B4275 Cardiff Road - the old main route to Cardiff before the A4059 road was built - between Aberdare and Mountain Ash. It is the most south-easterly named settlement that for postal reasons comes under the town of Aberdare.
