'Salamander III' was a British unrealised operation by the Special Operations Executive to attack U-boats, depot ships and other vessels in the Søvdefjord area of German-occupied Norway using 'sleeping beauty' motorised submersible canoes to approach the targets and attach limpet mines (9/18 September 1944).

The operation was cancelled as a result of objections by the Special Intelligence Service that it would threaten the security of its station on Guskøy south of Ålesund.
