George Powell (died 1823) was an English sealer, explorer and amateur naturalist. He captained three sealing expeditions to the Antarctic Ocean between 1818 and 1822. During the first expedition, in 1818 and 1819, he captained the sloop Dove and visited South Georgia and Kerguelen Islands. His second expedition, now captaining Eliza, lasted from 1819 until 1821, during which time he visited the Falkland Islands and the South Shetland Islands.
