Pliska Ridge is a three-peaked ridge rising to 667 m (2,188 ft) in eastern Livingston Island in the South Shetland Islands, Antarctica. Its central and highest summit, Pliska Peak, is located 2.48 km (1.54 mi) east-northeast of Willan Nunatak, 1.81 km (1.12 mi) southeast of Burdick Peak, 3.53 km (2.19 mi) south-southwest of Mount Bowles, 3.68 km (2.29 mi) west-southwest of Kuzman Knoll, and 3.61 km (2.24 mi) northwest of Mount Friesland. The feature is 1.6 km (0.99 mi) long and 500 m (1,600 ft) wide, its axis trending due east-west, with precipitous southern slopes. It is ice-covered except for segments of its easternmost peak and is bounded to the northwest by Orpheus Gate, to the north by the head of Perunika Glacier, to the east by Nesebar Gap, and to the south and west by the head of Huntress Glacier, the latter flowing 6 km (3.7 mi) southwestwards into False Bay.
