Du Rangneng (841–893), courtesy name Qunyi, formally the Duke of Jin, is an official of the Chinese dynasty Tang Dynasty, serving as a chancellor during the reigns of Emperor Xizong and Emperor Xizong's brother Emperor Zhaozong.

Early in Emperor Zhaozong's reign, against Du's recommendations, Emperor Zhaozong plans a campaign against the warlord Li Maozhen and puts Du in charge of the campaign.

After Li subsequently defeats the imperial forces, he marches on the capital Chang'an and demands Du's death, and Emperor Zhaozong is forced to order Du to commit suicide.
