Mount Newhall is a landmark of the Dutch Harbor area set 2.25 miles (3.62 km) east of Unalaska on Unalaska Island of the Aleutian Islands.

Topographic relief is significant as the summit rises over 1,900 feet (579 meters) above tidewater in approximately 1.3 miles (2.1 km).

The mountain's toponym was a local name published in 1951 on an U.S. Geological Survey map and has been officially adopted by the United States Board on Geographic Names.

[2][4] Dr. Albert Warren Newhall (1872–1929) and his wife Agnes were early residents of Unalaska who managed the Jesse Lee Home in Unalaska in the late 1800s and early 1900s.

According to the Köppen climate classification system, Mount Newhall is located in a subpolar oceanic climate zone with cold, snowy winters, and cool summers.
