Cwmamman or Cwmaman is a community in Carmarthenshire, about 12 miles north of Swansea in southwest Wales.

As coal-mining boomed during the late 19th century two adjoining villages grew up in the valley, known as Glanamman to the west and Garnant to the east.

[3] In contrast, four Methodist chapels were constructed in Glanamman before St Margaret's church was built in 1933.

There are two tiers of local government covering Cwmamman, at community and county level: Cwmaman Town Council (Cyngor Tref Cwmaman) and Carmarthenshire County Council (Cyngor Sir Gâr).

[4][5] The town council is based at the Community Centre on High Street in Glanamman.
