Kumano (熊野) was one of four Mogami class of heavy cruisers in the Imperial Japanese Navy, serving in World War II. She was named after the Kumano River Kii Peninsula on the island of Honshu in central Japan. The Mogami-class ships were constructed as "light cruisers" with five triple 6.1-inch dual purpose guns. They were exceptionally large for light cruisers, and the barbettes for the main battery were designed for quick refitting with twin 8-inch guns. In 1937 all four ships were "converted" to heavy cruisers in this fashion. Kumano served in numerous combat engagements in the Pacific War, until she was eventually sunk by carrier aircraft from Task Force 38 while she was undergoing repairs at Santa Cruz, Zambales, Philippines, in November 1944.

The Mogami class (最上型) was a ship class of four cruisers built for the Imperial Japanese Navy (IJN) during the 1930s. They were initially classified as light cruisers under the weight and armament restrictions of the London Naval Treaty. After Japan abrogated that agreement, all four ships were rearmed with larger guns and reclassified as heavy cruisers. All participated in World War II and were sunk.
