The Sikorski Glacier is a small glacier in the north-eastern part of the Noville Peninsula, Thurston Island, Ellsworth Land, Antarctica. It flows north-east to the Bellingshausen Sea between Mount Palmer and Mount Feury. It was first roughly delineated from aerial photos taken by the USN's Operation Highjump in 1946–47. It was named by the Advisory Committee on Antarctic Names (US-ACAN) for Stephen Sikorski, electronics technician on USS Glacier, who assisted in setting up an automatic weather station on Thurston Island during the USN's Bellingshausen Sea Expedition in February 1960.
