Liu E (simplified Chinese: 刘鹗; traditional Chinese: 劉鶚; pinyin: Liú È, 18 October 1857 — 23 August 1909), courtesy name/"zì": "Tieyun" (T'ieh-yün) (鐵雲), was a Chinese scholar, entrepreneur, and writer of the late Qing era.

Liu was a native of Dantu (modern day Zhenjiang). In the government he worked with flood control, famine relief, and railroads. He became disillusioned with official ideas of reform and became a proponent of private economic development modeled after western systems. During the Boxer Uprising he speculated in government rice, distributing it to the poor. He was cashiered for these efforts, but shrewd investments had left him wealthy enough to follow his pioneering archaeological studies and to write fiction.

He collected five thousand oracle bone fragments, published the first volume of examples and rubbings in 1903, and correctly identified thirty-four oracle bone script characters.

One of Liu's best known works is The Travels of Lao Can.

Liu was framed for malfeasance related to his work during the Boxer Rebellion and was exiled in 1908, dying within the next year in Ürümqi, Xinjiang.
