The Admiralty Mountains (alternatively Admiralty Range) is a large group of high mountains and individually named ranges and ridges in northeastern Victoria Land, Antarctica.

To their east they are bounded by the Southern Ocean, Robertson Bay, the Adare Peninsula and the Ross Sea.

[2][3][4] The southern tip of the mountains joins to the Hallett Peninsula to the north of Tucker Inlet on the Ross Sea.

Moubray Bay is to the north of the Hallett Peninsula, and receives several glaciers that drain the southeast of the range.

To the north of this bay, glaciers drain the northeast of the mountains directly into the Southern Ocean.
