Zheng Keshuang, Prince of Yanping (Chinese: 鄭克塽; Pe̍h-ōe-jī: Tēⁿ Khek-sióng; 13 August 1670 – 22 September 1707), courtesy name Shihong, art name Huitang, was the third and last ruler of the Kingdom of Tungning in Taiwan in the 17th century. He was the second son of Zheng Jing and a grandson of Koxinga (Zheng Chenggong). After surrendering to the Qing dynasty in 1683, he was ennobled as Duke of Hanjun, and lived the rest of his life in Beijing.

Zheng Kezang (1662–1681), birth name Qin (欽) or Qinshe (欽舍), was the crown prince and regency of the Kingdom of Tungning. Kezhang was the eldest son of Zheng Jing and Chen Zhaoniang, and his grandparents were Koxinga and Princess Dong.

The Kingdom of Tungning, also known as Tywan, was a dynastic maritime state that ruled part of southwestern Taiwan and the Penghu islands between 1661 and 1683. It is the first predominantly ethnic Han state in Taiwanese history. At its zenith, the kingdom's maritime power dominated varying extents of coastal regions of southeastern China and controlled the major sea lanes across both China Seas, and its vast trade network stretched from Japan to Southeast Asia.
