Lower Plenty is a suburb of Melbourne, Victoria, Australia, 16 km north-east from Melbourne's Central Business District. Its local government area is the City of Banyule. At the 2011 Census, Lower Plenty had a population of 3,782.
Lower Plenty, in earlier times part of Eltham, almost certainly got its name from the Lower Plenty Toll Bridge, built in 1860 to collect tolls across the Plenty River. This bluestone bridge still stands as part of the Lower Plenty Trail. A report of a court case, in The Argus newspaper, dated 1 May 1879, reveals two lads, Corkhill and Hodgson, "broke the windows of the old tollhouse, Lower Plenty bridge", some 19 years after the bridge was built.
The suburb is bounded by the Plenty River in the west until it joins the Yarra River, which forms the southern boundary. Fitzsimons Lane forms the eastern boundary and Airlie Road north of Main Road (a continuation of Lower Plenty Road from the west) forms the northern boundary.
