Wang Yanzheng (王延政) (died 951?), known as Tiande Emperor (天德帝) after his era name of Tiande, formally Prince Gongyi of Fu (福恭懿王), also known during Min as the Prince of Fusha (富沙王), was the last ruler of the Chinese Five Dynasties and Ten Kingdoms Period state Min. In 943, he, then in civil war with his brother Wang Yanxi (Emperor Jingzong), declared himself emperor of a new state of Yin at his base Jian Prefecture (建州, in modern Nanping, Fujian), but after Wang Yanxi was killed by the general Zhu Wenjin, who was himself assassinated thereafter, Wang Yanzheng reclaimed the title of Emperor of Min. His reign would last less than three years overall, though, as Min's northwestern neighbor Southern Tang bore down militarily on him and forced his surrender, ending Min.
