Zeng Jiongzhi (Chinese: 曾炯之; pinyin: Zēng Jiǒngzhī; Wade–Giles: Tseng Chiung-chih, April 2, 1898 – November 1940), also rendered as Chiungtze C. Tsen in English, was a Chinese mathematician born in Nanchang, Jiangxi, who proved Tsen's theorem. He was one of Emmy Noether's students at the University of Göttingen. He died in Xikang in 1940.

One of his research interests was quasi-algebraic closure. In that area he proved the theorem that took his name (Tsen's theorem).
