Ammanford is a town and community situated in Carmarthenshire, Wales, within the United Kingdom. Located at coordinates 51.8000, -3.9930, it serves as a significant settlement in the region. The area operates under a two-tier local government structure, comprising the Ammanford Town Council and the broader Carmarthenshire County Council. Its administrative center is housed in the Ammanford Town Hall on Iscennen Road, reflecting its role as a civic hub for the surrounding communities of Llandybie, Betws, and Llanedi.

The settlement originated as Cross Inn, named after an inn at a road convergence point. During the nineteenth century, growth in the tinplate and anthracite coal trades spurred expansion around this location, which later became known as Ammanford Square. In November 1880, public meetings resolved to change the name to Ammanford, meaning Ford of the River Amman, a decision welcomed by residents after the Great Western Railway adopted the name for its station in June 1883.

Historical events have deeply shaped the town's character, notably the 1925 Ammanford Anthracite Strike where miners controlled the area for ten days. The Miners' Memorial on Quay Street commemorates those who died in pit disasters, constructed from slate and sandstone layers representing coal seams. The town also hosted the National Eisteddfod in 1922 and 1970, cementing its cultural heritage. Local sports teams, including Ammanford RFC formed in 1887, contribute to the community's identity.

Ammanford offers diverse visitor appeal through its sporting events and natural surroundings. Parc Garnant Golf Club and Glynhir Golf Club provide extensive courses nearby, while local football and rugby teams play in regional leagues. The town was granted Fairtrade Town status in 2002, renewed in 2003. Nonconformist chapels like Ebeneser and Bethany highlight its religious history, particularly during the 1904–1905 Welsh Revival, attracting those interested in the area's social and spiritual past.

The community had a population of 5,439 as of 2021, with the wider built-up area holding 8,285 residents. Transport links include the A483 and A474 roads, alongside Ammanford railway station on the Heart of Wales Line connecting to Llanelli, Swansea, and Shrewsbury. The economy has historically relied on coal and tinplate industries, now complemented by tourism and retail. Its location five miles from the M4 end facilitates access for visitors exploring Carmarthenshire.
