Lü Simian (Chinese: 呂思勉; pinyin: Lǚ Sīmiǎn; Wade–Giles: Lü Ssu-mien; February 27, 1884 – October 9, 1957) was a Chinese historian. He was a former professor and history department head at Kwang Hua University, a predecessor of the East China Normal University in Shanghai. Lü took the courtesy name Chéngzhī (诚之) and wrote under the pseudonym Núniú (驽牛). His students included famous historians Ch'ien Mu and Yang Kuan. Historian Yan Gengwang (严耕望) considered Lü one of the four greatest modern Chinese historians, along with his student Ch'ien Mu, Chen Yuan, and Chen Yinke.

In 1926 Lü was invited to teach at Kwang Hua University by his friend and the school's headmaster Qián Jībó (钱基博). Lü remained at the school, which later became part of East China Normal University, until his death.

Lü was born in Wujin (now Wujin district of Changzhou city) in China's Jiangsu province. At the age of 15 he entered the county school. In the second year he began teaching himself history. He later became a member of the Doubting Antiquity School which was a group of scholars and writers who showed doubts regarding the authenticity of pre-Qin texts.

His former residence in Changzhou is a protected property open to the public, offering numerous artifacts from his life displayed in the restored building.^[1]
