Pontnewynydd is a predominantly working class suburb of Pontypool, Torfaen, in Wales. It should not be confused with Pontnewydd in nearby Cwmbran.
It lies in between Pontypool to the south and Snatchwood to the north. The area of Torfaen is historically industrial and the Pontnewynydd Iron Works once employed many people in the area. This works became known as the Partridge Jones and John Paton (PJ & JP) Iron Works. During the Second World War the works produced much of the corrugated iron for the Anderson shelters that were constructed throughout the country as makeshift air raid shelters. It finally closed in 1961, along with a number of other local works when the Llanwern Steelworks opened in Newport.
The Monmouthshire Canal which ran from Newport to Pontnewynydd was authorised by an Act of Parliament on 3 June 1792. The section of canal from Pontymoile to Pontnewynydd was drained in the 1850s and the canal bed used to lay a railway line, which was eventually extended to Blaenavon.
There is a small selection of shops and a car repairs garage. In 2001 the population was 1527 (49.5% Male, 50.5% Female) with an electorate of 1,174.
The main social club built for the workers at the PJ & JP works was located adjacent to the works on Hanbury Road and continued long after the works closed. An example of its prominence in the area is that the club was the official host to the visiting South African Springboks rugby touring team during 1961 when they played at Pontypool. The club hosted regular live entertainment and boxing bouts.
The local Pontnewynydd Sports & Social Club has recently ended a very long association with The Royal British Legion. Membership applications have soared since this happened and it is looking forward to being the premier entertainments centre in the village. Trevethin AFC who play their football in the village, and who head their division, use the Club as its base.
