Abersychan is a large suburb of Pontypool, Torfaen in South Wales. It lies in the narrow northern section of the Afon Llwyd valley. The town includes three schools, Abersychan Comprehensive School, Victoria Primary School and St. Francis' R.C. Primary School (although the latter is due to close, along with St. Alban's R.C. Primary School, to be replaced by the new Padre Pio R.C. Primary School in Pontypool) and various shops/other amenities.
Abersychan was the birthplace of the Rt. Hon. Paul Murphy, MP for Torfaen and Roy Jenkins, Baron Hillhead.
Abersychan now constitutes a community and electoral division of the county borough of Torfaen. The area was anciently part of the parish of Trevethin, in Monmouthshire. On June 3, 1864 Abersychan was constituted a local government district, governed by a local board. In 1894 Abersychan became an urban district and civil parish. The urban district was abolished in 1935, with most of its area passsing to Pontypool urban district, and a small area going to Abercarn UD.
In 1974 the area became part of the borough of Torfaen, in the new local government county of Gwent. A community of Abersychan was formed in 1985, but to date no community council has been formed. In 1996 Torfaen became a unitary authority.
The Abersychan community includes Abersychan, Cwmavon, Garndiffaith, Pentwyn, Talywain, Varteg, and Victoria Village.
