Cynonville Halt railway station served the village of Cynonville, in the historical county of Glamorganshire, Wales, from 1912 to 1956 on the Rhondda and Swansea Bay Railway.

It first appeared as Cynon Colliery and Pontrhydyfen Argoed in the 1899 fare table.

It originally had no platforms so workers had to board and alight from the trackside.

Its name later appeared as Cynon New Pit and it was changed to Cynonville Halt when it opened publicly.

[1] The track bed is now a cycle path and the platforms still survive.
