Laugharne /ˈlɑːrn/ (Welsh: Talacharn) is a town located upon the south coast of Carmarthenshire, Wales, lying upon the estuary of the River Tâf.
Laugharne is within the electoral ward and community of Laugharne Township (Welsh: Treflan Lacharn). The ward includes Laugharne, the village of Pendine and Pendine Sands. It was the civil parish corresponding to the marcher borough of Laugharne. A predominantly English-speaking area, just south of the Landsker Line, it is bordered by the communities of Llanddowror, St Clears, Llangynog and Llansteffan.

From 1949 until his death in 1953, Laugharne was the home of Dylan Thomas and is thought to have been the inspiration for the fictional town of Llareggub in Under Milk Wood, though topographically it is more thesame to New Quay where Thomas mostly lived whilst he wrote the story.
