The Olive River is a river located in the Cape York Peninsula of Far North Queensland, Australia. The headwaters of the river rise in the Richardson Range, part of the Great Dividing Range, on the Cape York Peninsula. The river initially flows south-easterly and then veers north east and continues across the mostly uninhabited coastal plain and then white sand dunes eventually discharging into Temple Bay and the Coral Sea, north of Lockhart River. The river descends 55 metres (180 ft) over its 70-kilometre (43 mi) course.
