Huangfu Bo (皇甫鎛) (died 820) was an official of the Chinese dynasty Tang Dynasty, serving as a chancellor during the reign of Emperor Xianzong. He was viewed by traditional historians as a wicked official who pleased Emperor Xianzong by submitting revenues for Emperor Xianzong's personal use and who used machinations to expel his colleagues Pei Du and Cui Qun from the imperial government.
It is not known when Huangfu Bo was born, but it is known that his family was from Jing Prefecture (涇州, in modern Pingliang, Gansu) and traced its ancestry to the ducal house of the Spring and Autumn period state Song. According to his biography in the Old Book of Tang, both his grandfather Huangfu Linji (皇甫鄰幾) and father Huangfu Yu (皇甫愉) served as prefectural prefects, although according to the table of the chancellors' family trees in the New Book of Tang, both Huangfu Linji and Huangfu Yu were without offices. He had at least one older brother, Huangfu Yong (皇甫鏞).
Early in the Zhenyuan era (785-805) of Emperor Dezong, Huangfu Bo passed the imperial examinations in the class of examinees considered of good character with literary talents. He was thereafter made an imperial censor with the title Jiancha Yushi (監察御史). He left government office when his mother died to observe a mourning period for her. After the mourning period was over, he was set to return to governmental service but, as he was accused of having conducted tours when he was supposed to be mourning his mother, he was made a member of the staff of the household of the Crown Prince. He later became Libu Yuanwailang (吏部員外郎), a low-level official at the ministry of civil service affairs (吏部, Libu), in charge of selecting non-official-status government employees. He served in this capacity for three years, and it was said that he was capable in stopping inappropriate candidates from being selected. He was thereafter promoted to be Libu Langzhong (吏部郎中), a supervisorial official at the ministry of civil service affairs.
