The Japanese destroyer Yūnagi was one of nine Kamikaze-class destroyers built for the Imperial Japanese Navy (IJN) during the 1920s. During the Pacific War, she participated in the occupation of the Gilbert Islands and the Battle of Wake Island in December 1941 and then the occupations of New Guinea and the Solomon Islands in early 1942.

The Kamikaze-class destroyers were a class of nine destroyers of the Imperial Japanese Navy. Some authors consider the Nokaze, Kamikaze and Mutsuki classes to be extensions of the Minekaze-class destroyers, and the Kamikaze class is sometimes referred to as the "Kiyokaze class" to distinguish it from the earlier World War I-era destroyer class of the same name. Obsolete by the beginning of the Pacific War, the Kamikazes were relegated to mostly secondary roles. Most ultimately were lost to U.S. submarines.
