Pentre Galar (or Pentregalar, Pentre-Galar) is a small settlement in the Preseli Mountains south of the village of Crymych, north Pembrokeshire, Wales, on the A478 Cardigan to Tenby road.

The land slopes from Crugiau Dwy at a height of 359 metres (1,178 ft) in the west down towards the valley of Afon Gafel, a tributary of the River Taf.

[7] The land surrounding Pentre Galar was enclosed by Act of Parliament in 1812, resulting in the orderly layout of small, rectangular fields.

[5] The Royal Commission records the name Pentre Galar from an early 20th century map,[8] and has in its collection aerial photographs of old field banks taken in 1999.

[16] The Preseli transmitting station was constructed in 1962 near the summit of Crugiau Dwy, and by 1973 was broadcasting colour TV to West Wales, fairly late in comparison with the rest of the UK, owing to the sparse population in the area it served.
