SS Delhi was a steamship of the Peninsular & Orient Line (P&O) that was lost off Cape Spartel, northern Morocco, at the entrance to the Strait of Gibraltar, on 12 December 1911. Among the passengers was Alexander Duff, 1st Duke of Fife, whose subsequent death in Egypt was ascribed to ill-health caused during the wreck, and his family, the Princess Royal and daughters Princesses Alexandra and Maud.

Cape Spartel is a promontory in Morocco about 1,000 feet (300 m) above sea level at the entrance to the Strait of Gibraltar, 12 km west of Tangier. It is the northwesternmost point of the African continent. Below the cape are the Caves of Hercules.
