Mount Duneed is a suburb of Geelong, Victoria, Australia. It is divided between the City of Greater Geelong and Surf Coast Shire local government areas.
Much of the locality north of Lower Duneed Road is part of the large Armstrong Creek Growth Area, which was opened up for urban development from 2010. With the gazetting of the suburb Armstrong Creek in February 2012, Mount Duneed's southern boundary between Surf Coast Highway and Horseshoe Bend Road follows the boundary of the Armstrong Creek Urban Growth Area. The area north of Boundary Road, south of the Warrnambool railway line and west of the Surf Coast Highway, formerly part of Grovedale, became part of Mount Duneed.
