Rhoshill (also known as Rhos-hill) is a hamlet on the A478 road, in the community and parish of Cilgerran, in Pembrokeshire, South-west Wales.

Rhoshill is a collection of about twenty houses at an elevation of 150 metres (490 ft), surrounded by farmland, and the local name given to the hill which runs westwards from the hamlet.

An area of the hill is marked as Mynydd Crogwy, but the significance of this is not clear as there is no direct translation (although crogwyr means hangman).

[3] It is home to an agricultural engineering company and a number of other business including a herb grower (medicinal and culinary) and holiday lets.

Neuadd y Dderwen (The Oak Hall) is a carbon neutral 250-seat building that has attracted such performers as Catrin Finch and Shân Cothi and is supported by Western Solar whose CEO, Dr Glen Peters, is the owner of Rhosygilwen.
