The Government of the Ryukyu Islands (琉球政府 Ryūkyū Seifu?) was the self-government of native Okinawans during the American occupation of Okinawa. It was created by proclamation of the United States Civil Administration of the Ryukyu Islands (USCAR) on April 1, 1952 and was abolished on May 14, 1972 when Okinawa was returned to Japan. The government consisted of an executive branch, a legislative branch, and a judicial branch. Members of legislature were elected. The legislature made its own laws, and often had conflicts with USCAR, who could overrule their decisions.
The government was headed by a Chief Executive (行政主席 Gyōsei Shuseki?). From 1952 to 1960, the Chief Executive was assigned by USCAR. He was then assigned the leader of the dominant party of the legislature (1960–66), elected in the legislature (1966–68), and elected by the citizens (1968–72).
In 1945, the Okinawa Advisory Council was established by order of the United States Armed Forces, to administer the Okinawa Islands, the prefecture office of which had been eliminated as a result of Battle of Okinawa. The surviving prefecture offices, including those of Miyako Subprefecture and Yaeyama Subprefecture, established their own independent administrations. On February 2, 1946, after the decision to partition Japan's territory south of the 30th parallel north, Ōshima Subprefecture (including the Amami Islands and Tokara Islands) separated from the jurisdiction of Kagoshima Prefecture and came under the command of the United States Military Government of the Ryukyu Islands. On August 4, 1950, after multiple reorganizations, the Government of the Okinawa Islands, Government of the Miyako Islands, Government of the Yaeyama Islands, and Government of the Amami Islands were established.
