Mount Llana (Bulgarian: връх Ляна, romanized: vrah Lyana, IPA: [ˈvrɤx ˈʎanɐ]) is the ice-covered peak rising to 1300 m at the north extremity of Urda Ridge on Clarence Island in the South Shetland Islands, Antarctica. It is connected to Jerez Peak by Soyka Saddle, and surmounts Bersame Glacier to the west and Highton Glacier to the east.

The peak is named after the Spanish mariner José de la Llana who probably discovered Shag Rocks, South Georgia in 1762.
