The Đại Việt sử ký (Vietnamese: [ɗâːjˀ vìət ʂɨ᷉ kǐ], chữ Hán: 大越史記, Annals of Đại Việt) is the official historical text of the Trần dynasty, that was compiled by the royal historian Lê Văn Hưu and was finished in 1272. Considered the first comprehensive account of the history of Vietnam, the 30-volume book covered the period between 207 BC to 1225 AD in Vietnamese history, from Triệu Đà, the first king of the Triệu dynasty, to Lý Chiêu Hoàng which was the empress regnant and the last ruler of the Lý dynasty. Although it was lost during the Fourth Chinese domination in Vietnam, the contents of the Đại Việt sử ký, including Lê Văn Hưu's comments about various events in the history of Vietnam, were used by other Vietnamese historians as a base for their works, notably the Đại Việt sử ký toàn thư by Ngô Sĩ Liên.
