Yang Fugong (楊復恭) (died 894), courtesy name Zike (子恪), formally the Duke of Wei (魏公), was an eunuch official of the Chinese dynasty Tang Dynasty, playing key roles in the imperial administrations of Emperor Xizong and Emperor Xizong's brother Emperor Zhaozong. He was later suspected by Emperor Zhaozong of power-grabbing and removed, and afterwards encouraged his adopted sons/nephews Yang Shouliang, Yang Shouxin (楊守信), Yang Shouzhen (楊守貞), and Yang Shouzhong (楊守忠) into resisting the imperial government together. They were, however, defeated by the general Li Maozhen and captured while in flight; they were then delivered to the capital Chang'an and executed.
It is not known when Yang Fugong was born. He was originally surnamed Lin (林) until he, who apparently became an eunuch in his youth, became an adopted son of the eunuch Yang Xuanyi (楊玄翼), who was a director of the palace communications (Shumishi) during the middle of Emperor Yizong's Xiantong era (860-874). (He was thus adoptive cousin of another later-prominent eunuch, Yang Fuguang, who was the adopted son of Yang Xuanyi's adoptive brother Yang Xuanjie (楊玄价).) Yang Fugong was literate and well-learned, and subsequently successively served as a eunuch monitor for several imperial armies. During the Pang Xun rebellion of 868-869, Yang Fugong served as the eunuch monitor of the Heyang Circuit (河陽, headquartered in modern JIaozuo, Henan), and after Pang's rebellion was suppressed, Yang was credited and recalled to the capital Chang'an to serve as the palace-government liaison (宣徽使, Xuanhuishi). After Yang Xuanyi died in 870, Yang Fugong left governmental service for some time to observe a mourning period for him, but soon was recalled to serve as a director of palace communications.
