Endurance Glacier is a broad glacier north of Mount Elder, draining south-east to the south coast of Elephant Island in the South Shetland Islands of Antarctica, and is the main discharge glacier on the island. It was named by the UK Antarctic Place-Names Committee after HMS Endurance (Captain P.W. Buchanan, Royal Navy), which anchored off the glacier on several occasions in support of the Joint Services Expedition to Elephant Island, 1970–71.
