The Australian swamp rat (Rattus lutreolus), also known as the eastern swamp rat, is a species of rat native to the coasts of southern and eastern Australia.

The Australian swamp rat grows to have a body length of approximately with a tail length of approximately and a mass of about It has a stocky build with black brown fur and black feet. Its ventral surface is cream to brown color and it has small ears nearly concealed by hair. The tail is dark grey, scaly and sparsely haired.

The swamp rat is found near the coast of south and eastern Australia. It occurs in lowland country from Fraser Island down the coast of New South Wales and Victoria to the Mount Lofty Ranges in South Australia. A subspecies velutinus can be found in Tasmania, and another subspecies lacus lives in isolated patches of high altitude rainforest near Atherton, Queensland. The preferred habitat of the swamp rat is thick vegetation along watercourses and in swamps. The dense vegetation of islands above the high water mark is also suitable. Areas prone to fire tend not to be recolonised. The swamp rat can be seen at places like the Healesville Sanctuary, where they live in the grounds.

Behaviour is partly nocturnal and diurnal so it is active during the day and at night. It is thought that the species does not collect the sufficient amount of food throughout the night and must also collect vegetation during the day.

The rats reach sexual maturity around August and start to breed come October.
