Heirisson Island is an artificially created island in the Swan River in Western Australia at the eastern end of Perth Water, within the suburb of East Perth. It occupies an area of 285,600 square metres (70.6 acres), and is connected to the two foreshores by the Causeway and the Boorloo Bridge. The next upstream island is Kuljak Island, then Ron Courtney Island, with no islands in the Swan River downstream between Heirisson Island and the Indian Ocean other than the artificial islet in Elizabeth Quay.

Before development, there were several small islands, surrounded by mudflats. Over the years, dredging and reclamation has created a single island, which is now a landscaped nature reserve, with a 2-kilometre (1.2 mi) walking path. The Noongar name for the area is Matagarup (meaning 'leg deep'), which has been retained for the single island after reclamation.

Heirisson Island is listed on the Western Australia Department of Aboriginal Affairs' Register of Aboriginal Sites, as ID 3589.
