Dungkar Lozang Trinlé (Tibetan: Dung-dkar blo-bzang 'phrin-las, sometimes spelled Dungkar Lobsang Trinlay, 1927–21 July 1997) was one of the most important Tibetan historians of the 20th century.

He was born in the southeastern district of Kongpo. At age four, he was recognized as the eighth reincarnation of Dungdkar Rinpoche, the spiritual leader of Dungdkar Monastery. After completing his studies and earning a geshé degree from Sera Monastery, he left monastic life.

In 1959, during a period of unrest in Tibet, he was teaching far from Tibet. He later gave up his religious vows, married, and faced accusations. During the Cultural Revolution, he worked as a laborer in the fields. After being cleared of wrongdoing, he returned to Beijing, remarried, and worked at the Central Nationalities Institute. There, he wrote a book titled Snyan ngag la 'jug tshul tshig rgyan rig pa'i sgo 'byed ("Opening the door to the study of ornamentation for writing poetry," 1982). In the mid-1980s, he returned to Lhasa and taught history at Tibet University, supporting efforts to teach in both Tibetan and Chinese. As official attitudes toward Tibet became stricter, he fell out of favor with authorities. His decision to write about Tibet from a Marxist perspective in his books had already caused some Tibetan exiles to distance themselves from him.

He is remembered for his major work, Dung dkar tshig mdzod ("Dungkar's Encyclopedia" or "White Conch Encyclopedia"), last reprinted in 2002, and for Bod-kyi Chos Srid Zung-'brel Skor Bshad-pa ("The Merging of Religious and Secular Rule in Tibet," 1981/3), a religious history focusing on politics and society. This book was translated into English in 1991 by Chen Guansheng.
