Yang Fugong (died 894), courtesy name Zike, formally the Duke of Wei, is a 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 is later suspected by Emperor Zhaozong of power-grabbing and removed, and afterwards encourages his adoptive sons/nephews Yang Shouliang, Yang Shouxin, Yang Shouzhen , and Yang Shouzhong into resisting the imperial government together.

They are, however, defeated by the general Li Maozhen and captured while in flight; they are then delivered to the capital Chang'an and executed.
