Mambourin was a railway station located on the Geelong line in Victoria, Australia. It was opened in 1888 and closed in 1893.
Since 2020, a proposal has existed to build a railway station in the newly developed suburb of Mambourin.
Mambourin station opened in November 1888 as "Pearce's Bros Siding" to serve a nearby quarry. It was renamed to Mambourin in 1892.
The station was closed in 1893. The quarry was later served by a siding from Manor station, which was parallel with the main line, until it ceased operating around the 1930s.
In 2020, houses began to be constructed in Mambourin, which is being developed as a new suburb and experiencing rapid growth. The suburb was planned to built around a new train station on the existing Regional Rail Link. , there have been no updates from the Victorian Government on the station's funding or development.
