The McGregor Range (71°58′S 167°51′E / 71.967°S 167.850°E / -71.967; 167.850 (McGregor Range)) is a mountain range 13 nautical miles (24 km; 15 mi) long in the south-central Admiralty Mountains, Antarctica. The range is circumscribed by the flow of the Tucker Glacier, Leander Glacier, Fitch Glacier and Man-o-War Glacier.

Exploration and naming

The McGregor Range was partially mapped by the NZGSAE, 1957–58. It was mapped by the United States Geological Survey (USGS) from surveys and U.S. Navy aerial photography, 1960–63. It was named by the United States Advisory Committee on Antarctic Names (US-ACAN) for Cdr. Ronald K. McGregor, United States Navy, leader of Antarctic Support Activities at McMurdo Station, winter party 1962.

The McGregor Range extends north–south to the west of Fitch Glacier, which runs south to join Man-o-War Glacier, which in turn runs southwest to join Tucker Glacier. On its east the range is bounded by Leander Glacier, which runs along its north and west sides to join Tucker Glacier. Mount Brazil is in the south of the range.

A small peak in the Admiralty Mountains that rises above and close west of Shadow Bluff at the junction of the Tucker Glacier and Leander Glacier. Climbed by the geological team of the NZGSAE, 1957-58, in January 1958, and named from association with Shadow Bluff and nearby Mount Midnight.
