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 Town Hall station in central Melbourne to Sunbury station in the city's north-west, serving 16 stations via Parkville, 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 10–20 minutes during off-peak hours. Trains on the Sunbury line run with a seven-car formation operated by High Capacity Metro Trains.

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.

On 1 February 2026, the Sunbury Line was through routed with the Pakenham and Cranbourne lines, running through the Metro Tunnel via Town Hall station.
