Mount Ulmer (77°35′S 86°09′W / 77.583°S 86.150°W / -77.583; -86.150) is a prominent peak situated 2 miles north of Mount Washburn in Gromshin Heights on the east side of northern Sentinel Range in Ellsworth Mountains, Antarctica. It surmounts the head of Vicha Glacier to the east and Newcomer Glacier to the west.

The mountain was discovered in his trans-Antarctic flight on November 23, 1935, by Lincoln Ellsworth who called it "Mount Mary Louise Ulmer", after his wife. The peak was reidentified by comparing Ellsworth's photograph with those taken in 1959 by the U.S. Navy.

The peak of the mountain rises to a total of 3,800 meters.
