The Brisbane River is the longest river in south east Queensland, Australia, and flows through the city of Brisbane, before emptying into Moreton Bay. John Oxley was the first European to explore the river who named it after the Governor of New South Wales, Thomas Brisbane in 1823. The penal colony of Moreton Bay later adopted the same name.

Early travellers along the waterway admired the natural beauty, abundant fish and rich vegetation along its banks. From 1862 the Brisbane River has been dredged for navigation purposes. The river served as an important carriageway between Brisbane and Ipswich before a railway linking the towns was built in 1875. By the late 1920s, water quality in the river had significantly deteriorated. The river contains excess nutrients, hydrocarbons, pesticides, bacteria and is murky.

The river travels 344 km (214 mi) from Mount Stanley. The river is dammed by the Wivenhoe Dam, forming Lake Wivenhoe, the main water supply for Brisbane. The waterway is a habitat for the rare Queensland lungfish, Brisbane River cod and bull sharks. The largest ship built on the river was the Robert Miller. The 66,000 tonne vessel became un-moored in the 1974 Brisbane flood. While not the highest experienced along the river since European settlement, this flood was the most damaging. Major floods also occurred in January 2011 and multiple times during 1893.

Extensive port facilities have been constructed on the Fisherman Islands, now known as the Port of Brisbane. There are 16 major bridges that cross the river. The Clem Jones Tunnel, opened in 2010, is the river's first underground crossing for road transport. The CityCat ferry service collects and delivers passengers along the inner-city reaches of the river.
