Radomir Knoll (Radomirska Mogila \'ra-do-mir-ska mo-'gi-la\) rises to approximately 300 m in Prespa Glacier, eastern Livingston Island in the South Shetland Islands, Antarctica. It is formed by the south extremity of an offshoot of Friesland Ridge, Tangra Mountains that extends to the south-southeast from St. Cyril Peak and surmounts Chavei Cove to the south and southwest.

The feature is named after the Bulgarian town of Radomir.
