Compton Glacier is a glacier, 3 nautical miles (6 km) long, flowing northeast from the lower slopes of the Big Ben massif to the northeast side of Heard Island in the southern Indian Ocean.

Since the ANARE survey of 1947/48, the glacier has retreated significantly, exposing much more of Compton Lagoon.

[8] Evidence for significant loss was recorded as early as 1963, with an expedition describing the glacier as no longer smooth, but crevassed.

[10] The lower reaches of this glacier were charted and named Morgan's Iceberg on an 1860 sketch map compiled by Captain H.C. Chester, American sealer operating in the area during this period.

The feature was surveyed in 1947/48 by the Australian National Antarctic Research Expeditions, who applied the name Compton Glacier for G.S.
