Ardglass railway station was the terminus of the Downpatrick, Killough and Ardglass Railway, which ran from Belfast south to Newcastle, County Down in Northern Ireland.
Opened by the Downpatrick, Killough and Ardglass Railway, it became part of the Belfast and County Down Railway. The station closed to passengers in 1950, by which time it had been taken over by the Ulster Transport Authority.
The site was extant but the station buildings mostly roofless and derelict in 2017.
