The Mortlock River is a river in the Wheatbelt of Western Australia.
The headwaters of the river rise near Belmunging then flow in a northerly direction crossing the Goldfields Road and continuing in a north westerly direction to finally flow parallel to the Northam York Road and crossing Great Eastern Highway. The river discharges into the Avon River, of which it is a tributary, just west of Northam.
The river was named after the surveyor Henry Mortlock Ommanney in the 1830s. Ommanney was the first European to discover the river during an expedition through the area in 1835.[3]
There are three tributaries of the Mortlock River; Mortlock River North, Mortlock River East and Meenaar South Creek.
The river is saline and delivers the most salt (approximately 91 tonnes per year) into the Avon River.
