The Warburton Highway is a 34 kilometre west–east semi-rural highway starting on the eastern fringes of Melbourne, Victoria (Australia) at the Maroondah Highway just after Lilydale, connecting Melbourne to the Yarra Valley wine region and its towns, as well as Melbourne's closest mountain peak to receive regular snowfall, Mount Donna Buang. The entire road falls within the Shire of Yarra Ranges local government area and is wholly managed by VicRoads. It is a single carriageway for its entire length, being completely sealed since 1941, with one lane in each direction and occasional overtaking lanes being provided. Speed limits range from 50 to 60 km/h through townships and 70–80 km/h elsewhere. Because of the lack of the standard 100 km/h rural speed limit and high traffic volumes, Victoria Police maintain a high level of patrol and vigilance.

Maroondah Highway is a major east–west thoroughfare in the eastern suburbs of Melbourne, and a highway connecting the north-eastern fringes of Melbourne to the lower alpine region of Victoria, Australia.
