McLeod Glacier is a glacier long, flowing in a southeasterly direction into Clowes Bay on the south side of Signy Island, in the South Orkney Islands off Antarctica. It was named by the UK Antarctic Place-Names Committee in 1954 for Michael McLeod, following a survey by the Falkland Islands Dependencies Survey in 1947. On 12 December 1821, the cutter Beaufoy under McLeod sailed to a position at least west of the South Orkney Islands, where a chart annotation indicates that land was sighted, possibly Coronation Island.
