Dục Đức (chữ Hán: 育德, IPA: [zùkp ɗɨ́k]; born Nguyễn Phúc Ưng Ái, 23 February 1852 – 6 October 1883), was Emperor of Vietnam for three days, from 20 to 23 July 1883.

However, the Tam Cung, an alliance of powerful palace women, favored Dục Đức, and convinced the regents to alter the will and appoint him Emperor.

Other contemporary historians make no mention of this episode and say that Dục Đức was not executed but rather was left to die in captivity, a likelier sequence of events considering that he lived for another three months.

[4] Open protest of the regents' actions came from one senior official, Phan Đình Phùng, but he was quickly arrested and stripped of his position.

[1] Modern Vietnamese historians generally regard emperors from Dục Đức to Bảo Đại as puppets controlled by the French colonialists.
