Zheng Jing (鄭經, 1642-1681) was the son of Zheng Cheng-Gong.

After the conquest of Taiwan in 1661 by his father, Zheng Jing controlled the military forces in Xiamen and Quemoy on his father's behalf. Upon the death of his father six months later, Zheng Jing ascended the throne as the King of Taiwan. For the next nineteen years, he tried to provide sufficiently for the local inhabitants and reorganizing their military forces in Taiwan. Contact with the Kangxi Emperor from the mainland by sending ambassadors was frequent.

Under Qing pressure, Zheng Jing had a great time struggling to defend Xiamen, Quemoy and the Pescadores islands, which he had eventually lost them over the years, mainly due to their minuscule army forces which were insufficient to defend the Qing.

Zheng Jing committed suicide in 1681 in a battle with the Qing empire. His son, Zheng Ke-Shuang , succeeded him.
