Hayes Hill is a small scoria cone in Donnybrook, approximately 30 km north of Melbourne, Victoria, Australia.
It is on the eastern edge of the Newer Volcanics Province.
Hayes Hill is considered a regionally significant geological site as a source of the lava flows that follow the ancestral Merri and Darebin Creeks and Yarra River through the northern suburbs of Melbourne into the CBD.
