George Powell (1794–1824) was an English sealer, explorer and amateur naturalist. He captained three sealing expeditions to the Antarctic Ocean between 1818 and 1822. Powell was born in London. During his first expedition, in 1818 and 1819, he captained the sloop Dove and visited South Georgia and Kerguelen Islands. His second expedition, captaining Eliza, lasted from 1819 until 1821, during which time he visited the Falkland Islands and the South Shetland Islands. Both Powell Island and Powell Basin are named after him. He died in Tonga.
