The Logan River (Yugambeh: Dugulumba) is a perennial river in the Scenic Rim, Logan and Gold Coast local government areas of the South East region of Queensland, Australia. The 184-kilometre-long river is one of the dominant waterways in South East Queensland that drains the southern ranges of the Scenic Rim and empties into Moreton Bay after navigating the City of Logan, a major suburban centre located south of Brisbane. The catchment is dominated by urban and agricultural land use. Near the river mouth are mangrove forests and a number of aquaculture farms.
The river rises below Mount Ernest on the southern slopes of the Scenic Rim, part of the Great Dividing Range and forms in the Mount Barney National Park, near the Queensland – New South Wales border, below Mount Lindesay. The river flows generally north by northeast, joined by eleven minor tributaries, before heading east and eventually emptying into Moreton Bay. Its principal tributaries are the Albert River which joins it just east of Beenleigh; Teviot Brook which begins at Mount Superbus and joins the Logan River at Cedar Pocket; and Burnett Creek which is subverted by the Maroon Dam west of Rathdowney. The river descends 380 metres over its 184-kilometre course.
