This glacier was named after US Arctic explorer Robert Peary (1856 - 1920).

The Peary Glacier is located in the Lauge Koch Coast, Melville Bay.

[3] It originates in the western Greenland ice sheet and flows southwestwards between the Rink Glacier to the northwest and the King Oscar Glacier to the southeast.

[2] Its terminus lies east of Cape Murdoch, northeast of the Balgoni Islands and Thalbitzer Næs in Melville Bay.

[4] Unlike the neighboring King Oscar Glacier, it does not produce many icebergs.
