The Kuma-class light cruisers (球磨型軽巡洋艦, Kuma-gata keijun'yōkan) were a class of five light cruisers built for and operated by the Imperial Japanese Navy (IJN). The Kuma-class cruisers proved useful in combat operations ranging from the Aleutian Islands to the Indian Ocean throughout World War II.

The Kuma-class was followed by the very similar Nagara class.
