Opalchenie Peak (Bulgarian: връх Опълчение, romanized: vrah Opalchenie, IPA: [ˈvrɤx opɐɫˈt͡ʃɛniɛ]) is the peak rising to 4,503.5 metres (14,775 ft)^[1] at the south extremity of the ice-covered Vinson Plateau, Sentinel Range in the Ellsworth Mountains, Antarctica. It is of low topographic prominence, just 63 metres (207 ft),^[1] with parent summit Fukushima Peak (4,634 metres (15,203 ft)). The feature has a partly ice-free summit and south slopes, where two parallel ridges descend steeply southwestwards with Donnellan Glacier flowing in between and Mount Slaughter rising on the more southerly ridge.^[2] The northerly ridge was climbed up to the summit plateau by American Robert Anderson in November 1992, and subsequently used to establish a new route to Mount Vinson in 2003.^[3][4] Opalchenie Peak overlooks Vinson Plateau on the north, Craddock Massif on the southeast and upper Nimitz Glacier area on the southwest.

The peak is named after the Bulgarian Volunteer Force in the 1877-1878 Russo-Turkish War and the Macedonian-Adrianople Volunteer Force in the 1912-1913 Balkan Wars, ‘opalchenie’ being the Bulgarian for ‘volunteer force’.^[2]
