Merri Creek is a waterway in southern parts of Victoria, Australia, which flows through the northern suburbs of Melbourne. It begins near Wallan and flows south for 70 km until joining the Yarra River at Dights Falls.
The area where the creek meets the river was traditionally the location for large gatherings of the Wurundjeri people and is thought to have been the location for one of the earliest land treaties in Australia between Indigenous Australians and European settlers. The creek was the site of heavy industrial use throughout much of the 20th century, being home to quarries, landfills and accepting waste runoff from neighbouring factories.
