Langwarrin was a railway station on the Stony Point line, which is part of the Melbourne rail network. It was located between Leawarra and Baxter, serving the suburb of Langwarrin.
Langwarrin station opened in 1888, serving the newly-established Langwarrin Military Reserve.
In June 1981, the station was closed after the line's passenger services between Long Island Junction and Stony Point station were withdrawn.
Although the line reopened in 1984, Langwarrin station remained closed, and most traces of the station were removed by 1988. , the only remains of the station is platform mound, which is located off McClelland Drive inbetween Tea-Tree Track and the Centre Break track.
Public Transport Victoria announced in 2014 that it was investigating the possibility of reinstating a station at Langwarrin and sought community feedback on three possible station sites, including the location of the former station.
In 2018, the Morrison federal government committed to $228 million in funding towards electrifying and duplicating the line between Frankston and Baxter. The project would incorporate extending the Metro rail from Frankston to Langwarrin, building a new Langwarrin station, and building a park and ride next to the station.
