The Okinawan language or Central Okinawan is a Northern Ryukyuan language spoken primarily in the southern half of the island of Okinawa, as well as in the surrounding islands of Kerama, Kumejima, Tonaki, Aguni and a number of smaller peripheral islands. Central Okinawan distinguishes itself from the speech of Northern Okinawa, which is classified independently as the Kunigami language. Both languages are listed by UNESCO as endangered.

The Ryukyuan languages , also Lewchewan or Luchuan, are the indigenous languages of the Ryukyu Islands, the southernmost part of the Japanese archipelago. Along with the Japanese language and the Hachijō language, they make up the Japonic language family.
