The Logan River 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 (114 mi)-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.
