Trap (or Trapp) is a hamlet in the county of Carmarthenshire in southwest Wales, located on the western border of the Brecon Beacons National Park, around four miles southeast of the town of Llandeilo. It is unclear whether the name – which often appears as Trapp on maps, although the spelling with a single p is generally preferred locally – refers to a fish-trap, a water-trap (mill-leat), or, given that the village is in Cwm Lladron ("robbers' valley"), an ambush point.The Afon Cennen flows through the village and is bridged there by the road from Ffairfach to Drefach. One mile to the east, and visible from the village, are the remains of Carreg Cennen Castle, whilst to the south is the rocky Carreg Dwfn, the westernmost hill of the national park. The remains of Capel Dewi, a medieval chapel, are situated to the east of the road south of the village.
