Momi was a Matsu-class destroyer of the Imperial Japanese Navy (IJN) built during World War II. Completed in late 1944, the ship was designed as an anti-submarine escort and defended convoys between Japan and its occupied territories during the war. She was sunk with the loss of all hands on 5 January 1945 by an American torpedo bomber in the South China Sea.

The Matsu-class destroyers were a class of destroyer built for the Imperial Japanese Navy (IJN) in the late stages of World War II. The class was also designated the Type-D Destroyer . Although sometimes termed Destroyer escorts, they were larger and more capable than contemporary United States Navy destroyer escorts or the Imperial Japanese Navy kaibōkan vessels.
