Kumejima (久米島町, Kumejima-chō, Okinawan: Kumishima) is a town located in Shimajiri District, Okinawa Prefecture, Japan.

Kumejima's main industries are sugar cane (sato-kibi), tourism, and deep seawater products.

In 1945, Japanese soldiers killed 20 inhabitants suspected of being close to the U.S. forces, including a baby and children.

[4] An area of 119 km2 (46 sq mi) of land and sea is protected as the Kumejima Prefectural Natural Park and 255 ha (630 acres) of wetland have been designated a Ramsar Site.

[13] In order to maintain and preserve the historic estate, there is a 300 yen entry fee for adults, payable at the house.

Due to the deep seawater resource, Kumejima now has the largest market share of Sea Grapes and Kuruma Prawns in Japan.

[16] In March 2013, Okinawa Prefecture completed the world's only fully operational Ocean Thermal Energy Conversion Demonstration Facility.
