St Hilary Platform was a short-lived station in the Vale of Glamorgan in South Wales.

The station was one of four 'platforms' opened on the branch to cater for the new railmotor service.

The station was not very conveniently situated with regards to the village which it claimed to serve.

It was a considerable distance away, and passengers travelling from the station to the village had to climb a steep hill.

Only Trerhyngyll and Maendy Halt (originally Trerhyngyll and Maendy Platform) survived beyond 1920 with its later 'pagoda'-style shelter still standing in 1959 well after closure to passenger traffic in 1951.
