Li He (c. 790–791 – c. 816–817) was a Chinese poet of the mid-Tang dynasty. His courtesy name was Changji, and he is also known as Guicai and Shigui.

Alongside Li Bai and Li Shangyin, he is known as one of the "Three Lis" of the Tang Dynasty. As a representative figure during the transition from mid-Tang to late-Tang poetic styles, his works often express a deep sense of frustration over being born in an unfavorable era and convey his inner turmoil. His poetry reflects his relentless pursuit of ideals and ambitions while also shedding light on the fragmentation caused by warlordism, the dominance of eunuchs in court politics, and the severe oppression suffered by the common people.
