Cadman Glacier is a glacier, 1.5nmi wide at its mouth and about 7nmi long, flowing northwestward into the head of the southern arm of Beascochea Bay south of Plas Point on the west side of the Antarctic Peninsula.
The glacier was discovered and roughly surveyed in 1909 by the French Antarctic Expedition under Jean-Baptiste Charcot. It was surveyed in 1935 by the British Graham Land Expedition (BGLE), led by John Rymill, and later named for John Cadman, 1st Baron Cadman of Silverdale, who contributed toward the cost of the BGLE, 1934–37.
