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 in height.
The MV Akka was lost, after running onto the Gantocks on 9 April 1956. The PS Waverley ran aground on the rocks on 15 July 1977, with 715 passengers on board.
