Robert Moresby (15 June 1794 – 15 June 1854) was a captain of the East India Company's Bombay Marine/Indian Navy who distinguished himself as a hydrographer, maritime surveyor and draughtsman. As a Lieutenant under Commander Thomas Elwon, Moresby was part of a two-ship exercise engaged (from 1829 to 1832) in charting the dangerous waters of the Red Sea. Later, he also charted some coralline archipelagoes of the Indian Ocean, such as the Maldives, Laccadives and Chagos in the 1820s and '30s. This work ensured that the route from Europe to the East Indies became viable for the new steam vessels.
