Cotter River, a perennial river of the Murrumbidgee catchment within the Murray-Darling basin, is located in the Australian Capital Territory, Australia. The Cotter River, together with the Queanbeyan River, is one of two rivers that provides potable water to the Canberra and Queanbeyan region.
The river rises on the eastern slopes of the Brindabella Ranges in the south-west of the Australian Capital Territory (ACT), within Namadgi National Park, and flows generally north, joined by six minor tributaries, including Paddys River, before reaching its confluence with the Murrumbidgee River, near Casuarina Sands, west of the suburb of Weston Creek. The river descends 1,300 metres (4,300 ft) over its 76 kilometres (47 mi) course.
The traditional custodians of the land surrounding the Cotter River are the Aboriginal people of the Ngunnawal clan.
The river was named in honour of Garrett Cotter, an Irish-born convict who was transported to Australia for "the term of his natural life". Cotter was banished from Lake George to the western side of the Murrumbidgee River in 1832. He built a house near the headwaters of the river that was later to bear his name. Cotter was granted a ticket-of-leave in 1843; given a conditional pardon in 1846 that gave him freedom of movement, except in Britain and Ireland; and later lived in Michelago.
