This category features postage stamps issued for the Ryukyu Islands during the United States occupation, spanning roughly 1948 to 1972, when the islands were administered by the United States following World War II. Although geographically part of Japan, the Ryukyus operated under a separate postal system during this period, producing distinctive stamp issues not valid in the United States.

Common designs include local landscapes, traditional Okinawan culture, folklore motifs such as Shisa guardians, agriculture, and everyday island life, as well as issues reflecting postwar reconstruction and U.S. administration. Many stamps were denominated in cents and printed with bilingual or English text, highlighting their unique political status at the time.

Collected for their transitional nature and historical significance, Ryukyu Islands stamps represent a fascinating intersection of Japanese culture and American administration, making them an important specialty area within both U.S. possessions and Japanese-related philately.
