Sunbury railway station is a commuter, regional railway station and the terminus of the suburban Sunbury line and the regional Deniliquin line, part of the Melbourne and Victorian railway networks. It serves the north-western suburb of Sunbury, in Melbourne, Victoria, Australia. Sunbury station is a ground level premium station, featuring two side platforms. It opened on 10 February 1859, with the current station provided in 2012.

The station is also serviced by V/Line services to Bendigo and Echuca. A disused station Rupertswood is located between Sunbury and Clarkefield.

Sunbury station opened on 10 February 1859 as a terminus, with the railway line not extended further for two years. The three-track yard dates from that time, and was unique in Victoria. There was a large goods shed on its southern side, a large silo on its northern side, as well as sheep and cattle ramps and yards. There was also housing for railway staff, including two houses in Horne Street, and the stationmaster's house in Brook Street, which were all demolished in the 1980s.

Until 1981, proper interlocking of the signals and point work did not exist, and the station was not fully interlocked until 1998, when Solid State Interlocking was provided. On 16 April 2005, that interlocking was abolished, as part of the Regional Fast Rail project.

In late 1993, the station was refurbished, with upgrades included an enclosed booking lobby, an air-conditioned waiting room, repainted station buildings and landscaping of the garden area around the station. In 2005, as part of the Regional Fast Rail project, the layout of the station was again altered.

On 18 November 2012, the station was added to the metropolitan network, when the line from Watergardens was electrified. The station was also upgraded as part of those works. Electrification of the line to Sunbury was first proposed in the 1970s, along with a new station along the Sunbury bank north of the Jackson Creek bridge, to serve the Goonawarra housing estate. However, after a drop in population estimates, that idea was abandoned.

In 1940, flashing-light warning signals were provided at the former Gap Road level crossing, which was located at the up end of the station, with boom barriers provided in 1983. In 2005, the level crossing was modified as part of the Regional Fast Rail project and, in 2012, was modified again, as part of the electrification of the line to Sunbury. On 30 November 2018, the Level Crossing Removal Project announced that the level crossing would be grade separated, with the road passing underneath the railway line. The project was brought forward from 2025, and was completed in September 2022.
