The Division of La Trobe is an Australian Electoral Division in the state of Victoria. It is located in the outer eastern/south-eastern suburbs of Melbourne. It was originally located closer to the city, but redistributions moved it further south-east. It originally included the suburbs of Croydon, Dandenong, Ferntree Gully and Ringwood. As of 2005, the Division is roughly Y-shaped, centred on the Cardinia Reservoir.
