Dunnet Head (Scottish Gaelic: Ceann Dùnaid) is a headland in Highland, on the north coast of Scotland.

From this line, the headland projects westward and northward into the Atlantic Ocean and the Pentland Firth and shelters the more southerly waters of Dunnet Bay.

The peninsula is north-east of the burgh of Thurso, and on a clear day, it affords views of the islands of Stroma to the east, and Hoy and the Orkney Mainland, 15 km (9 miles) away to the north, across the Pentland Firth.

Near the Dunnet Head lighthouse are minor fortifications built during World War II to protect the naval base at Scapa Flow, including a Chain Home Low radar station and a bunker used by the Royal Observer Corps during the Cold War.

Dunnet Head lochs are restocked every two years with brown trout fry; fishing by permit is between 1 April and early October.
