The Sunbury line is a commuter railway line in the city of Melbourne, Victoria, Australia. Operated by Metro Trains Melbourne, it is the city's fifth longest metropolitan railway line at 40.3 kilometres (25.0 mi). The line runs from Flinders Street station in central Melbourne to Sunbury station in the city's north-west, serving 18 stations via North Melbourne, Sunshine, St Albans, and Watergardens. The line operates for approximately 19 hours a day (from approximately 5:00 am to around 12:00 am) with 24 hour service available on Friday and Saturday nights. During peak hour, headways of up to 5 minutes are operated with services every 20–30 minutes during off-peak hours. Train sets typically used on the Sunbury line are the Comeng and Siemens Nexas trainsets and, for two morning peak services, the High Capacity Metro Train.

The Victorian Railways began services in February 1859 on the line originally built to serve the town of Bendigo by the Melbourne, Mount Alexander and Murray River Railway Company. The line was progressively electrified over time, with electrification to St Albans in 1921, to Sydenham in 2002, and finally to Sunbury in 2012.

Since the 2000s, due to the heavily utilised infrastructure of the Sunbury line, improvements and upgrades have been made. Works have included replacing sleepers, upgrading signalling technology, two line extension projects, the construction of new stations, the removal of level crossings, the introduction of new rolling stock, and station accessibility upgrades.

Beginning in 2025, the Sunbury Line will be through routed with the Pakenham and Cranbourne line running through the Metro Tunnel via Town Hall station.
