The Stony Point line is a commuter railway line in the outer metropolitan area of Melbourne, Victoria, Australia. Operated by Metro Trains Melbourne, it is the only diesel service on the metropolitan network and, at 31 kilometres (19 mi), is the tenth-longest line. It is an extension of the Frankston line, with services running from Frankston station to Stony Point, serving 10 stations in all. The line is also used for freight services to the Port of Hastings.

The line was opened in three sections during 1888 and 1889. Only two stations have been added since its completion—Leawarra and Morradoo. In recent years, there have been proposals to extend the electrified Frankston line to Baxter.
