Princess Taiping (died 2 August 713) is a princess of the Chinese dynasty Tang Dynasty and her mother Wu Zetian's Zhou Dynasty.

She is the youngest daughter of Wu Zetian and Emperor Gaozong and is powerful during the reigns of her mother and her elder brothers Emperor Zhongzong and Emperor Ruizong (both of whom reign twice), particularly during Emperor Ruizong's second reign.

Eventually, however, a rivalry develops between her and her nephew, Emperor Ruizong's crown prince Li Longji, and after Emperor Ruizong yields the throne to Li Longji (as Emperor Xuanzong) in 712, the conflict comes to the political forefront, and in 713, Emperor Xuanzong, according to historical records, believing that she was planning to overthrow him, acts first, executing a large number of her allies and forcing her to commit suicide.
