The House of Nguyễn Phúc, also known as the House of Nguyễn Phước, is a family and a branch of the surname Nguyễn in Vietnam. Its members were the Nguyễn lords (1558–1777, 1780–1802) and emperors of the Nguyễn dynasty (1802–45). Its member Bảo Đại was also emperor of the State of Vietnam (1949–55) and Domain of the Crown (1950–55). Nguyễn Bặc (924–79), an official of the Đinh dynasty, was its founder.
Under Emperor Gia Long, the family's rule was not only restored, but extended to the whole of Vietnam in 1802, thus marking the start of the unified Nguyễn dynasty. The Nguyễn dynasty agreed to French supervision in 1883. In 1887, Vietnam became part of the Indochinese Union, which was administered by a French governor general.
