Li Yifu (Chinese: 李義府; 614–666) was a chancellor of the Chinese dynasty Tang Dynasty, during the reign of Emperor Gaozong. He became particularly powerful because of his support for Emperor Gaozong's second wife Empress Wu (later known as Wu Zetian) when her ascension was opposed by then-chancellors, and he had a reputation for treachery. He was also fully involved in the elimination of Empress Wu's political rivals and played an important role in it. In 663, on account of corruption, he was removed from his post and exiled, and in 666, after Emperor Gaozong had declared a general pardon but excepted the long-term exiles from the pardon, Li Yifu died in anger.
