Cotton Plateau (82°54′S 159°40′E / 82.900°S 159.667°E / -82.900; 159.667 (Cotton Plateau)) is a snow-covered plateau just east of the mouth of Marsh Glacier, in the Queen Elizabeth Range.

Cotton Plateau was named by the northern party of the New Zealand Geological Survey Antarctic Expedition (NZGSAE; 1961–62) for Sir Charles Cotton, noted New Zealand geomorphologist and authority on glacial landforms.

Cotton Plateau is in the west of the Queen Elizabeth Range, bounded by the Marsh Glacier to the west, the Prince of Wales Glacier and Hamilton Glacier to the east and the Princess Anne Glacier to the south. Features include, from north to south, Hochstein Ridge, Prince Edward Glacier, Panorama Point and The Palisades.

Mapped by the United States Geological Survey (USGS) from tellurometer surveys and Navy air photos, 1960-62. Named by the United States Advisory Committee on Antarctic Names (US-ACAN) for Manfred Hochstein, USARP glaciologist at Roosevelt Island, 1961-62, 1962-63 and 1963-64.

The name was suggested by the Holyoake, Cobham and Queen Elizabeth Ranges Part of the NZGSAE, 1964-65. Named for a geologist in the party, M. Gregory.

So named by the Holyoake, Cobham and Queen Elizabeth Ranges party of the NZGSAE (1964-65) because it affords an excellent view.
