Crymych (Welsh pronunciationⓘ) is a village of around 800 inhabitants[2] and a community (population 1,739) in the northeast of Pembrokeshire, Wales.

It is situated approximately 800 feet (240 m) above sea level at the eastern end of the Preseli Mountains, on the old Tenby to Cardigan turnpike road, now the A478.

Evidence of prehistoric occupation in the community is the Megalithic burial mound known as Crymych Wayside Barrow.

[8] It was announced in July 2023 that the Crymych Arms, which had been closed for 18 months, was to be reopened following a community grant of £210,000 from the UK government.

[9] Crymych's status as "capital" of the Preselau was confirmed in 1958, when Ysgol y Preseli, a secondary school covering a wide district, was opened.

Crymych stands at the meeting point of three (formerly Anglican) parishes: Llanfair-Nant-Gwyn to the north, Penrydd to the east and Llanfyrnach to the south.

[23][24][25] The complex is a joint venture between Pembrokeshire County Council, Hywel Dda Local Health Board and Family Housing Association Wales.

[28] To the southeast of Crymych, near the hamlet of Glandwr, is Lammas Ecovillage, a low-impact housing development.

[29] The Preseli TV and radio transmitting station is about 1.8 miles (3 km) SSW of Crymych.
