The Derung (also spelt Drung or Dulong) people (simplified Chinese: 独龙族; traditional Chinese: 獨龍族; pinyin: Dúlóngzú; endonym: [tɯɹɯŋ]) are an ethnic group. They form one of the 56 ethnic groups officially recognized by the People's Republic of China. Their population of 6,000 is found in the Nujiang Autonomous Prefecture of Yunnan province, in the Dulong valley. Another 600 can be found east of the Dulong valley, living in the mountains above the Nu Jiang (Salween River) near the village of Binzhongluo in northern Gongshan County.

The Derung speak the Derung language, a Sino-Tibetan language. Their language is unwritten; in the past the Derung have transmitted messages and have made records by making notches on wooden logs.

There are few documents about the origins of the Derung. It is known, nevertheless, that during the period of the Tang dynasty, the Derung were under the jurisdiction of the kingdoms of Nanzhao and Dali. Later on, from the Yuan dynasty to the Qing dynasty, the Derung were governed by the local heads of the Naxi. In 1913, the Derung helped to repel a British attack in the area. Until 1949 there were several names used for this ethnic group; they received names as Qiao during the Yuan dynasty and Qiu and Qu during the Qing dynasty.
