Vilkitsky Islands – a group of islands situated close to the Taymyr Peninsula in the entrance part of Terezy Klavenes Gulf, Laptev Sea, Russia. The group includes the islands: Udobny, Sredniy, Krayniy, Sliyanie, and some others. The islands were partially explored in 1919 by the participants of the Norwegian Polar Expedition on the “Maud” during the winter stay near Cape Chelyuskin (former Maud) (1918–1919). The islands were named by the commander of the expedition R. Amundsen in honor of the Russian hydrographer and geodesist, the Navy officer, B. A. Vilkitsky.
