SS Carnatic was a British steamship built in 1862-63 by Samuda Brothers at Cubitt Town on the Isle of Dogs, London, for the Peninsular and Oriental Steam Navigation Company (P&O). She operated on the Suez to Bombay run in the last years before the Suez Canal was opened. This route gave a fast, steamship-operated route from Britain to India, connecting with similar steamships running through the Mediterranean to Alexandria, with an overland crossing to Suez. The alternative was to sail round the Cape of Good Hope, a distance at which steam ships were not, in the early 1860s, sufficiently economical to be commercially competitive with sail.
