'Narcissus' was a British special forces operation by A Squadron, 2^nd Special Air Service to find and destroy an Axis artillery observation post which the Italians were thought to have established in a lighthouse in southern Sicily, and therefore likely to exercise a considerable effect on the progress of the land operations immediately following 'Husky' (i) (10 July 1943).

The party of 40 men was delivered from the infantry landing ship Royal Scotsman by landing craft to the beach on which it was believed the Axis forces had established an artillery position with its observation post in a lighthouse, but found no sign of Axis activity and was immediately evacuated.
