Dunmore railway station is a heritage-listed former railway station that was located on the South Coast railway line in Dunmore, City of Shellharbour, New South Wales, Australia. The station served the southern Wollongong suburb of Dunmore and indirectly Shellharbour and opened on 9 November 1887. The weatherboard station on Platform 2 dates from 1887. It is also known as the Shellharbour Railway Station Group, Shellharbour railway station and Dunmore Railway Station. The property was added to the New South Wales State Heritage Register on 2 April 1999. As part of the electrification of the line to Kiama in 2001, the existing crossing loop was extended north and received a platform, albeit built out of scaffolding materials with most trains continuing to use the original platform. The loop also provides access to Boral's Dunmore Quarry. There was previously a level crossing immediately south of the station. This was closed in the late-2000s as part of improvement works to the adjacent Princes Highway.
