The Taivoan (; ) or Tevorangh (; ) people or Shisha (), also written Taivuan and Tevorang, Tivorang, Tivorangh, are a Taiwanese indigenous people.
The Taivoan originally settled around hill and basin areas in Tainan, especially in the , which area the Taivoan called Tamani, later transliterated into Japanese 玉井 and later borrowed as Chinese Yujing. The Taivoan historically called themselves Taivoan, Taibowan, Taiburan or Shisha as endonyms.
According to some scholars, there should be more than 20,000 Taivoan people nowadays, estimated based on the records during Japanese rule of Taiwan, ranked as the second largest non-status indigenous people in Taiwan, only second to Makatao people.
Many scholars propose that the name of the island Taiwan actually came from the indigenous people's name, as the pronunciation of Taivoan is similar to Tayovan, the people that the Dutch met around the coast of Anping or the bay around Anping, which later became the name Taiwan. In addition, the Taivoan established a settlement called Taiouwang, which is the only indigenous community residing there whose name resembles Taiwan.
The Taivoan people are ethnically called "Taivoan" or "Tevorangh". While the former term comes from the self-identification of the indigenous people recorded by Japanese linguists in the early 20th century, the latter comes from one of the four main tribes or nations established by the Taivoan in the early 17th century, well-recorded by the Dutch and Chinese people in a couple of documents, in different spellings including Tevorang, Tevoran, Tefurang, Devoran, Tivorang, Tivorangh, and the like. Farrell also noted that the two terms "Tevorangh and Taivoan are probably dialectal variants of a common name (< *tayvura-n)".
In December 1628, George Candidius, the first missionary to Dutch Formosa, wrote that there were eight tribes around modern-day Tainan, including "Sinkan, Mattau, Soulang, Bakloan, Taffakan, Tifulukan, Teopan and Tefurang", among which "the most remote village is Tefurang, which lies between the mountains".
