The Senkaku Islands (尖閣諸島 Senkaku-shotō, variants: 尖閣群島 Senkaku-guntō and 尖閣列島 Senkaku-rettō), also known as the Diaoyu Islands (Chinese: 钓鱼岛及其附属岛屿; pinyin: Diàoyúdǎo jí qí fùshǔ dǎoyǔ; also simply 钓鱼岛) in China or Diaoyutai Islands (Chinese: 釣魚台列嶼; pinyin: Diàoyútái liè yǔ) in Taiwan, or the Pinnacle Islands, are a group of uninhabited islands in the East China Sea. They are located roughly due east of China, northeast of Taiwan, west of Okinawa Island, and north of the southwestern end of the Ryukyu Islands.

Following the discovery of potential undersea oil reserves in 1968 in the area and the 1971 transfer of administrative control of the islands from the United States to Japan, the latter's sovereignty over the territory is disputed by both the People's Republic of China (PRC) and the Republic of China (also known as Taiwan). China claims the discovery and ownership of the islands from the 14th century, while Japan had ownership of the islands from 1895 until its surrender at the end of World War II. The United States administered the islands as part of the United States Civil Administration of the Ryukyu Islands from 1945 until 1972, when the islands returned to Japanese control under the Okinawa Reversion Agreement between the United States and Japan.

The islands are disputed between China and Japan and between Japan and Taiwan. Despite the diplomatic stalemate between the China and Taiwan, both governments agree that the islands are part of Taiwan as part of Toucheng Township in Yilan County. Japan regards the islands as a part of the city of Ishigaki in Okinawa Prefecture, and acknowledges neither the claims of China nor Taiwan but has not allowed the Ishigaki administration to develop the islands.
