Emma was a merchant vessel launched at Calcutta in 1809 that served as a government armed ship in the British invasion of Île de France in 1810. In 1811 she sailed to England where she was sold. She then became a transport and later a whaler. Between 1815 and 1853 she made 11 whaling voyages. She was then sold and became a merchantman on the England-Australia run. Between 1851 and 1853 she made one more whaling voyage to the South Seas fisheries. She then returned to the England-Australia trade. In 1857 her home port became Hull, and she became a Greenland whaler, though that role may have begun as early as 1855. She was converted in 1864 to a screw steamer but was lost in April while seal hunting.
