Xenia Hill is the rocky hill rising to 96 m in the northeast extremity of Half Moon Island in the South Shetland Islands, Antarctica. It surmounts McFarlane Strait to the north and east, and Menguante Cove to the south-southeast. The area was visited by early 19th century sealers operating from nearby Yankee Harbour.
The feature's name appeared in a 2000 publication following Argentine ornithological research on the island, and in the 2005 and 2009 Bulgarian maps of Livingston Island.
