Ulupna Island, a river island, lies at the eastern end of Barmah National Park which is a part of the largest river red gum forest in Victoria, Australia. The island is bounded by the Murray River and its anabranch, Ulupna Creek.
It is located in Northern Victoria, with the nearest town being Strathmerton. The island is popular as a camping destination and is rich in wildlife, with many goannas, eastern grey kangaroos and koalas visible all year.
The Ulupna Island Flora Reserve is heritage listed as a place of natural significance on the Register of the National Estate. The Statement of Significance cites "Unlike the remainder of the Barmah forests, Ulupna Reserve has suffered remarkably little from the impacts of grazing and logging. Therefore it is an important reference area for studies of the impacts of these activities on the red gum forests of the region."
