Location of Annan River mouth in Queensland

The Annan River (Kuku Nyungkal: Yuku Baja) is a river located in the Wet Tropics of Far North Queensland, Australia.

The river rises in the Yorkey Range below Mount Romeo near Rossville, north-northwest of Wujal Wujal. The river flows generally in a north-westerly direction, joined by three minor tributaries that drain waters from the Trevethan Range before finally heading eastwards to Walker Bay. At its river mouth, the Annan River is joined by the Esk River and together the two rivers empty into the Coral Sea south of Cooktown. The river descends 568 metres (1,864 ft) over its 66-kilometre (41 mi) course and flows through the Black Mountain (Kalkajaka) National Park and the Annan River (Yuku Baja-Muliku) National Park. The river has a catchment area of 750 square kilometres (290 sq mi).

Being in a wet-dry tropical climate the river receives the majority of its approximately 1,800-millimetre (71 in) rainfall per year between the months of December and April, a period known as the wet season.

The river is crossed by the Mulligan Highway near Rossville and again closer to its mouth.

The river was given its gazetted name by an early Australian pastoralist and magistrate, John Jardine, who, on 11 November 1865, named it after the River Annan in Scotland, while on passage in the HMS Salamander.
