Heidelberg is a suburb of Melbourne, Victoria, Australia, 11 kilometres northeast of Melbourne's central business district. Its local government area is the City of Banyule. In 2016, Heidelberg had a population of 6,225.
Once a large town on Melbourne's outskirts, Heidelberg was absorbed into Melbourne as part of the latter's northward expansion after World War II. Heidelberg once had its own historic central business district including its own municipality in the former City of Heidelberg.
Heidelberg lends its name to the Heidelberg School, an impressionist art movement that developed in and around the town in the late 19th-century.
