Zhao Erxun (23 May 1844 – 3 September 1927), courtesy name Cishan, art name Wubu, was a Chinese political and military officeholder who lived in the late Qing dynasty.

In 1874, he sat for the palace-level examination and emerged as a jinshi, after which he was admitted to the Hanlin Academy as a bianxiu (編修; compiler and editor).

In 1893, he served as a prefect in Guizhou Province and was promoted to a daotai (道台; a type of military official).

In August 1904, he was recalled to the imperial capital, Beijing, to serve as acting Secretary of Revenue.

[citation needed] Han Suyin takes a different view and says that the main issue in the conflict was control over a planned railway that would have linked Sichuan to the rest of China.

He served as Viceroy of the Three Northeast Provinces until the Xinhai Revolution overthrew the Qing dynasty in early 1912.

His tomb is located at the north of Shenshan Village (神山村), Huaibei Town (懷北鎮), Huairou District, Beijing.
