Wu Wenjun (Chinese: 吴文俊; 12 May 1919 – 7 May 2017), also commonly known as Wu Wen-tsün, was a Chinese mathematician and academician at the Chinese Academy of Sciences (CAS).

Wu's ancestral hometown was Jiashan, Zhejiang. He was born in Shanghai and graduated from National Chiao Tung University in 1940. In 1945, Wu taught several months at Hangchow University (later merged into Zhejiang University) in Hangzhou.

In 1947, he went to France for further study at the University of Strasbourg. In 1949, he received his PhD, for his thesis Sur les classes caractéristiques des structures fibrées sphériques, written under the direction of Charles Ehresmann. Afterwards, he did some work in Paris with René Thom and discovered the Wu class and Wu formula in algebraic topology. In 1951 he was appointed to a post at Peking University. However, Wu may have been among a wave of recalls of Chinese academics working in the West following Chiang Kai-shek's ouster from the mainland in 1949, according to eyewitness testimony by Marcel Berger, as he disappeared from France one day, without saying a word to anyone.

In 1957, he was elected as an academician of the Chinese Academy of Sciences. In 1990, he was elected as an academician of the Third World Academy of Sciences.
