The Inner Circle Line was a steam era suburban railway line (later electrified) in Melbourne, Australia. It served the inner-northern suburbs of Parkville, Carlton North, Fitzroy North, and Fitzroy. At its closure, it ran from Royal Park station on the Upfield line in the west to a triangular junction with Rushall and Merri stations on today's Mernda line in the east. There was also a branch line to Fitzroy that opened at the same time.
