Skirrid Fawr, often referred to as just the Skirrid, is an easterly outlier of the Black Mountains in Wales. It forms the easternmost part of the Brecon Beacons National Park. The smaller hill of Ysgyryd Fach or "Little Skirrid" lies about 2+1⁄2 miles south. It is 486 metres high and lies just to the north-east of Abergavenny, Monmouthshire, about ten miles from the English border. The Beacons Way passes along the ridge.
