The Lewis Sound is a strait ( sound ) in the archipelago of the Biscoe Islands off the west coast of the Antarctic Peninsula . It runs in a northwest-southeast direction between Lavoisier Island and Krogh Island in the northeast and Watkins Island in the southwest. It connects the open Southern Ocean with the Crystal Sound .

Aerial photographs of this sea route were taken during the Falkland Islands and Dependencies Aerial Survey Expedition (1956–1957). The UK Antarctic Place-Names Committee named it in 1960, initially as Lewis Passage , after the British cardiologist Thomas Lewis (1881-1945), who studied the effects of temperature on the blood vessels of the skin.
