Cilgerran (previously Kilgerran or Cil-Garon) is both a village, a parish, and also a community, situated on the south bank of the River Teifi in Pembrokeshire, Wales.

Nearby are the hamlets of Llwyncelyn, Rhoshill, Cnwce, Pen-y-bryn, Carreg-wen and Pontrhydyceirt, and the villages of Llechryd and Boncath.

Cilgerran lies 50 metres (160 ft) above sea level on the southern bank of the River Teifi.

The stream Afon Plysgog which rises on nearby Rhoshill runs under the road to the west of Cilgerran to join the Teifi.

A mixture of woodland and pasture surrounds the town, which is strung out along a fairly level C-class road in an east–west orientation connecting with the A484 at Llechryd to the east and the A478 at Pen-y-bryn to the west.

The principal occupations throughout Cilgerran's history were farming, salmon fishing and slate quarrying.

Cilgerran County Primary School educates 139 (in 2013) children from nursery to 11 years old and serves several surrounding villages.

[14] The Cardiff Arms (19th century)[15] and Pendre Inn (18th century or earlier)[16] are both Grade II listed buildings; the Masons Arms (known locally as the Ramp Inn) is in Cnwce, a settlement to the east of Cilgerran.

With much of Cilgerran Castle in ruins, its picturesque nature and setting have attracted many artists including J. M. W. Turner.

The annual coracle races on the River Teifi were first held in 1950 and attract competitors from all over the world.

The river flows slowly through a wooded gorge below the castle making it attractive for canoeists and kayakers.

[22] A substantial degree of slate quarrying was carried out in and near Cilgerran, mostly situated on the south side of the River Teifi's gorge.

[26] The industry peaked in the late 19th century, its continuance until that time supported by the coming of the railway in 1869.
