Usnea Plug is a volcanic plug, 30 m from base to summit, rising to 117 m in the interior of Byers Peninsula, Livingston Island in the South Shetland Islands, Antarctica. The area was known to 19th century sealers.
The feature's name derives from the genus of lichen, Usnea, prevalent on the plug and in this vicinity, and results from geological work by an American field party in early 1969.
