Castlebythe Halt railway station served the village of Puncheston, Pembrokeshire, Wales, from 1928 to 1937 on the North Pembrokeshire and Fishguard Railway.
The station opened on 24 September 1928 by the Great Western Railway.
It was situated closer to Puncheston village than the original station was.
It only had 85–90 passengers a week; thus it closed on 25 October 1937.
