Dún Laoghaire Mallin railway station is a station in Dún Laoghaire.
The station has been named Mallin Station since 1966, after Michael Mallin, although it is usually referred to simply as Dún Laoghaire. It has two through platforms and one terminal platform and is served by DART services, the South Eastern Commuter line, and InterCity services to Rosslare Europort via Wexford.
Unusually, the station building is on a bridge above the platforms, in a setup similar to Leixlip Louisa Bridge railway station. The station has a ticket counter, automatic ticket machines and a small coffee shop/smoothie bar.
The station is next to Dún Laoghaire Ferryport, for Stena Line services to Holyhead.
