Udina is a volcanic massif in central Kamchatka, Russia. It has two cone-shaped volcanoes: Bolshaya Udina (2,920 meters) and Malaya Udina (1,945 meters). Malaya Udina sits at the eastern end and is a basaltic volcano with small lava domes on its slopes. Bolshaya Udina is the larger western cone, mainly made of andesite and featuring a lava dome on its southwestern flank. For a long time Udina was thought to be extinct, but in June 2019 Bolshaya Udina showed signs of activity and is now considered active. Udina is part of Kamchatka's Volcanoes, a UNESCO World Heritage site.
