The Boyne River is a river located in Central Queensland, Australia. The headwaters of the river rise in the Bobby Range, within the Great Dividing Range southwest of Miriam Vale. The river descends from the western slopes of the range and flows generally north by east parallel with the Gladstone-Monto Road through the Boyne Valley. The river enters Lake Awoonga where it flows east by north, crossed by the Bruce Highway near Riverview, and finally discharging into the Port Curtis and the Coral Sea. The river descends 371 metres (1,217 ft) over its 125-kilometre (78 mi) course, joined by thirteen tributaries from source to river mouth. The mouth is located between the twin towns of Boyne Island and Tannum Sands. A bridge was built to cross the river joining the two towns in 1980.
