Empress Wang (王皇后, personal name unknown) (died 724) was an empress of the Chinese dynasty Tang Dynasty. Her husband was Emperor Xuanzong. She was initially made empress after he became emperor in 712, but eventually lost favor to Consort Wu, partly because she never had a son. Her brother Wang Shouyi (王守一) tried to use magic to regain favor for her, but this was discovered, causing her to be deposed and Wang Shouyi to be forced to commit suicide in 724. She died soon thereafter.
It is not known when the future Empress Wang was born. Her father Wang Renjiao (王仁皎) traced his ancestry to the Liang Dynasty official Wang Shennian (王神念). She married Li Longji as his wife and princess while he was the Prince of Linzi during the reign of either his grandmother Wu Zetian or his uncle Emperor Zhongzong. After Emperor Zhongzong died in 710, Emperor Zhongzong's wife Empress Wei took power as empress dowager and regent, but was soon overthrown by Li Longji and Emperor Zhongzong's sister Princess Taiping. It was said that as Li Longji was planning the coup, Princess Wang participated in the planning and supported him in the endeavor. After the successful coup, Li Longji's father Li Dan the Prince of Xiang, a former emperor, returned to the throne (as Emperor Ruizong). Li Longji was created crown prince, and Princess Wang became crown princess. She did not have a son herself, so she raised his second son Li Siqian, born of his then-favorite consort Consort Zhao, as her son.
In 712, Emperor Ruizong passed the throne to Li Longji, who took the throne as Emperor Xuanzong. Crown Princess Wang was created empress. Her father Wang Renjiao was made the minister of husbandry (太僕卿), and was eventually given the honorific title of Kaifu Yitong Sansi (開府儀同三司) and created the Duke of Qi.
