Đinh Bộ Lĩnh (924–979) (r. 968–979), real name allegedly Đinh Hoàn (丁桓), was the founding emperor of the short-lived Đinh dynasty of Vietnam, after declaring its independence from the Chinese Southern Han dynasty. He was a significant figure in the establishment of Vietnamese independence and political unity in the 10th century. He unified Vietnam by defeating twelve rebellious warlords and became the first emperor of Vietnam. Upon his ascension, he renamed the country Đại Cồ Việt. Đinh Bộ Lĩnh was also known as Đinh Tiên Hoàng (丁先皇; literally "the Former Đinh Emperor").
