Edgell Bay () is a bay 1.5 nautical miles (2.8 km) long and wide, indenting the northeast side of Nelson Island, in the South Shetland Islands. This bay appears in rough outline on Powell's chart of the South Shetland Islands published in 1822. It was recharted during 1934-35 by DI personnel on the Augustine Edgell, RN.
