The Niohuru (Manchu: ᠨᡳᠣᡥᡠᡵᡠ ; Chinese: 鈕祜祿; pinyin: Niǔhùlù; Wade–Giles: Niu3-hu4-lu4; literally: "wolf" in Manchu) were a prominent Manchu clan during the Qing dynasty. The clan had inhabited the Changbai Mountains since as early as the Liao dynasty. The clan was well known during the Qing dynasty for producing a variety of consorts of all ranks for emperors, several of whom went on to become mothers to reigning emperors. Prominent people who belonged or trace heritage to the Niohuru clan including famed Manchu warrior Eidu, his son the high official Ebilun, the Empress Dowager Ci'an, the infamous corrupt official Heshen, and the contemporary concert pianist Lang Lang.
Written records of the Niohuru clan dates back to the Liao dynasty (907–1125), when it was known as the Dilie clan (敌烈氏) by Chinese transliteration. The current transliteration Niohuru came into being during the Ming dynasty. The Niohuru clan inhabited the Changbai mountains region of present-day Jilin province in northeast China (otherwise known as "Manchuria"), and also on the banks of the Songhua River and Mudan River.
