The Academy of Sciences Glacier (Russian: ледник Академии наук; Lednik Akademii Nauk) is a large ice cap on Komsomolets Island, Severnaya Zemlya, Russian Federation.

This glacier was named after the Soviet Academy of Sciences by the 1930–1932 expedition to the archipelago led by Georgy Ushakov and Nikolay Urvantsev.

[3] It covers almost two thirds of Komsomolets island, except for an unglaciated area at the northern end.

[4] This vast ice cap is located on the southern side of the island, stretching from coast to coast, with the Laptev Sea on its eastern side at Krenkel Bay, the Red Army Strait in the south and the Kara Sea on the west at Zhuravlev Bay.

[5] The Academy of Sciences Glacier is portrayed in the 2021 film The Tomorrow War as the site which a group attempts to prevent the escape of aliens from a ship, 28 years before they do, without detection and spread across the planet.
