Connex Melbourne was a train operator in Melbourne, Australia. Formed in July 1998 as Hillside Trains, a business unit of the Public Transport Corporation, it was privatised in August 1999 becoming a subsidiary of Connex.
In April 2004, it became the sole operator of Melbourne suburban rail services, taking over the services of M>Train. When the franchise was re-tendered, it was awarded to Metro Trains Melbourne from November 2009.
