Rosneath was a coastal parish located in the former Scottish county of Dunbartonshire, which disappeared following the Local Government (Scotland) Act 1974. The parish had an area of 34.7 sq. km (13.4 sq. miles). It was made up of the peninsula between Loch Long and the Gareloch and the one parish with which it shares a land boundary is Rhu or Row. There are settlements at Kilcreggan, Garelochhead, Clynder, Rosneath (village), Cove and Coulport.
It is now situated in the Argyll and Bute Council Area, some 4 miles (7 km) northwest of Helensburgh across the Gareloch and 6 miles (10 km) northwest of Greenock across the River Clyde in what is now the Inverclyde Council Area.
