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.

The mountain was discovered by Lincoln Ellsworth in his trans-Antarctic flight on November 23, 1935, 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.
