Following is a list of glaciers of Heard Island and McDonald Islands in Antarctica. This list may not reflect recently named glaciers in
Heard Island and McDonald Islands.
Context
Heard Island is a volcanic island in the
Southern Ocean that is 80% covered in ice.
The island is cold and steep, and experiences high levels of snowfall.
There are many glaciers, which descend for up to from up to down to sea level.
The larger glaciers lose as much as 80% of their volume through calving into the ocean, and they are not particularly sensitive to temperature changes.
Melting is a more significant factor in loss of volume for the smaller glaciers.
Spring temperatures in the 1980s were about higher than the average in 1946–54.
Comparison of air photographs from 1947 and early 1970 show that glaciers have generally retreated, particularly on the eastern flanks, and that they have narrowed on northern and windward western flanks.
The area covered by glaciers had shrunk from in 1947 to by 1988.
A visit to the island in Spring 2000 showed several glaciers had retreated further, including the Stephenson, Brown and Baudissin glaciers.
Other studies have also shown the glaciers are retreating.

Named after Ian Allison, glaciologist, Australian Antarctic Division, who carried out glaciological studies in this area in 1971 during the French-Australian Expedition.
Baudissin Glacier
A glacier, wide, flowing into the west part of

, west of Challenger Glacier, on the north side of Heard Island.
The glacier appears to have been first noted by a sketch in the narrative accompanying the scientific reports of the 1874 Challenger work along the north side of the island.
The GerAE under Drygalski, 1901-03, portrayed a single large glacier flowing into Corinthian Bay and named it after Admiral Count Friedrich Baudissin, a sponsor of the expedition.
In 1948 the ANARE determined that more than one glacier discharges into Corinthian Bay.
The
Antarctic Names Committee of Australia (ANCA) recommended in 1954 that Baudissin Glacier be adopted for the westernmost and largest of these glaciers. Not: Baudissen Glacier.
Brown Glacier
.
A glacier just south of
Round Hill on the east side of Heard Island.
Surveyed by ANARE in 1948. Named by ANCA for K.G. Brown, ANARE biologist on Heard Island in 1951.
Between 1947 and 2004 the Brown Glacier shrank in area by about 29% from to , with a corresponding reduction in volume. The change appears to be due to increased air temperatures during this period rather than any other factor.
Challenger Glacier
.
A glacier, wide, flowing into the east part of Corinthian Bay, east of Baudissin Glacier, on the north side of Heard Island.
The glacier appears to have been first charted by the GerAE under Drygalski, 1901-03, who portrayed a single large glacier flowing into Corinthian Bay.
In 1948 the ANARE determined that more than one glacier discharges into Corinthian Bay.
The ANARE applied the name Challenger Glacier to the easternmost of these glacier's to commemorate the work of the British Challenger expedition, 1873-76.
Compton Glacier

and
Fairchild Beach.
The lower reaches of this glacier were charted and named "Morgan's Iceberg" on an 1860 sketch map compiled by Capt. H.C. Chester, American sealer operating in the area during this period.
The feature was surveyed in 1948 by the ANARE, who applied the name Compton Glacier for G.S. Compton, assistant surveyor with the expedition. Not: Morgan's Iceberg.
Deacock Glacier
.
A glacier close west of
Lavett Bluff on the south side of Heard Island.
Surveyed by ANARE, 1948-63. Named by ANCA for W. Deacock, a member of ANARE on Heard Island in 1963.
