The Gantocks is a small group of rocks lying off Dunoon in the upper Firth of Clyde, West of Scotland.

A navigation beacon was constructed on the rocks circa 1886. The beacon is 44 feet (13 metres) in height.

The MV Akka was lost, after grounding on the Gantocks on 9 April 1956. The PS Waverley grounded on the rocks on 15 July 1977, with 715 passengers on board.

The Gantocks beacon was repainted and maintenance carried out during 2018.
