Bedwellty (Welsh: Bedwellte) is a small village in Caerphilly County Borough in south Wales.

The register of St Sannan's Church dates from 1624,[1] which qualifies Bedwellty as an ancient parish.

[2] Several towns based on the iron industry expanded within the parish boundary, including from west to east, Rhymney, Tredegar and Ebbw Vale, which gradually gained administrative independence from Bedwellty between the 1870s and 1890s.

The original ancient parish was very large,[3] including most of the upper Ebbw and Sirhowy valleys.

[6] A number of coal mining communities grew up in the parish, and in the 19th century these became separate local government units.

Bedwellty urban district included the hamlets and villages of Aberbargoed, Argoed, Blackwood, New Tredegar, and Pengam.

In 1926, Bedwellty and Mynyddislwyn urban districts formed the West Monmouthshire Omnibus Board[10] to ensure local control of bus services.
