Plenty Road is a major urban arterial road through the north-eastern suburbs of Melbourne, Victoria, Australia, from the inner suburb of Preston to the township of Whittlesea,[3][4] just outside the north-eastern suburban fringe of Melbourne.

[5] The AAMI Crash Index of 2020 listed it as the worst road in Australia.

[7] Plenty Road commences at the intersection of High Street and Dundas Street in Preston and heads in a north-easterly direction as a four-lane single carriageway inner suburban road, carrying the Route 86 tram line on the roadway.

At Albert Street intersection in Reservoir, it widens to a six-lane dual-carriageway road with speed limits varying between 60 km/h and 70 km/h, carrying the tram route within the median strip.

Just north of the Metropolitan Ring Road interchange in Bundoora, the tram route ends at Bundoora RMIT, which also provides access to the nearby Uni Hill Shopping Centre.
