Cui Shenji (崔神基), formally the Duke of Qingqiu (清丘公), was a Chinese official of the Tang dynasty and the Wu Zhou dynasty, briefly serving as chancellor during Wu Zetian's reign.
It is not known when Cui was born, but it is known that his family was from Bei Prefecture (貝州, part of modern Xingtai, Hebei).
When Wu Zetian was a favorite concubine of Emperor Gaozong, Cui was part of a court faction that supported her in her effort to displace Emperor Gaozong's first wife Empress Wang and later, after she did become empress, assisted in her effort to take vengeance on officials who opposed her ascension, including Emperor Gaozong's uncle Zhangsun Wuji.
As of 692, he was serving as the minister of vassal affairs (司賓卿, Sibin Qing), when Wu Zetian gave him the designation of Tong Fengge Luantai Pingzhangshi (同鳳閣鸞臺平章事), making him a chancellor de facto.
Just slightly over a month later, however, he, along with other chancellors Li Youdao, Wang Xuan, Yuan Zhihong, Li Yuansu, and other officials Kong Siyuan (孔思元), and Ren Linghui (任令輝), were falsely accused of crimes by Wu Zetian's secret police official Wang Hongyi.
