The Black Mountains (Welsh: Y Mynydd Du or Y Mynyddoedd Duon) is a group of hills on the England–Wales border. The larger Welsh part is located in south-east Powys and north-west Monmouthshire, and the smaller English part in western Herefordshire. The range lies approximately within a triangle defined by Abergavenny in the south-east, Hay-on-Wye in the north, and Llangors in the west; Talgarth and Crickhowell are also nearby.
The Welsh part of the Black Mountains is the easternmost of the four ranges of hills that comprise the Brecon Beacons National Park; it should not be confused with the westernmost, the similarly-named Black Mountain. The Black Mountains contain a peak called the Black Mountain, which is the highest point in southern England. The Gospel Pass road is the highest public road in Wales.
