Llanyrafon is a suburb of Cwmbran and a community in the county borough of Torfaen in south east Wales.

Sometimes written on old maps and documents as Lan-yr-avon, Llan-yr-avon, or Llanyravon, the name literally translates as "Church by the River".

[3] Llanyrafon lies to the east of the Afon Llwyd and Cwmbran town centre, west of the A4042 dual carriageway and south of Croesyceiliog.

Built in the late 1950s, Llanyrafon is mainly residential but does include a municipal golf course; 3-star Hotel (Commodore Hotel on Mill Lane - closed in 2011 and now demolished to make way for a new housing development); small shopping precinct known as Llanyrafon Lakeside Shops and the large Boating Lake Park & South Fields.

The X24, a major bus service operated by Stagecoach South Wales, runs through Llanyrafon from Cwmbran town centre to Newport.
