Llantood (formerly Llantyd, Llantwyd or Llan-Illtyd) is a hamlet and parish in Cilgerran community, north Pembrokeshire, Wales.

It consists of a few houses, farms and a parish church on an open hill agricultural area averaging 150 metres (490 ft) above sea level.

[1] Evidence of prehistoric occupation can be seen by the remains of fortifications at Penralltddu, a scheduled monument, and at Castell Felinganol (or Castellfelorganol).

Church records date back to 1674, and the parish was in the Hundred of Kilgerran (formed in 1536)[3] even though it was in the Cemais administrative area.

[2] A development of six sustainable homes at Glanrhyd was approved by the Pembrokeshire Coast National Park's planning committee in June 2014, with conditions that the buildings would be manufactured locally and free solar powered electricity would be provided.
