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.
The hill is located at -62.6694°N -61.1145°W, which is 1.28 km west-northwest of Nikopol Point, 1.83 km east-northeast of Sevar Point, 3.49 km east by north of Devils Point, 2.8 km southeast of Point Smellie, 4.07 km southwest of Basalt Lake and 3.96 km south-southwest of Chester Cone (British mapping in 1968, detailed Spanish mapping in 1992, and Bulgarian mapping in 2005 and 2009).
