Sealer Hill is a hill rising to 70 m in the southwest part of Byers Peninsula, Livingston Island in the South Shetland Islands, Antarctica. It surmounts Nikopol Point and Sevar Point to the east-southeast and west-southwest, respectively. The area was inhabited by 19th century sealers.
The feature was so named following geological work by BAS in 1975–76, from the presence of at least three crude stone huts built by sealers below the hill.
