Soviet submarine K-22 was a K-class submarine of the Soviet Navy during World War II. She was part of the Northern Fleet until her loss in 1943.
Operating against Axis shipping in Norwegian waters, K-22 focused on gunnery attacks with her artillery.
On 9 April 1942 she discovered the damaged submarine ShCh-421, which had been disabled by a mine. Her crew had sailed her out of a minefield using a crude sail built from a canvas cover. K-23 rescued ShCh-421s crew and then scuttled the disabled submarine with a torpedo.
On 7 February 1943, K-22 was sunk with all hands by an enemy mine. She had just previously been in contact with her base.
