Kyiso (Burmese: ကျဉ်စိုး, pronounced: [tɕɪ̀ɴsó]; c. 1000–1038) was king of Pagan dynasty from 1021 to 1038. According to the Burmese chronicles, Kyiso was a son of King Nyaung-u Sawrahan but raised by King Kunhsaw Kyaunghpyu. Kunhsaw married Nyuang-u's three chief queens, two of whom were pregnant and subsequently gave birth to Kyiso and Sokkate. Sokkate and Kyiso were raised by Kunhsaw as his own sons.
