The Tamang (; Devanagari: तामाङ; tāmāṅ), are a Tibeto-Burmese ethnic group of Nepal, Southern Bhutan and North India. In Nepal Tamang/Moormi people constitute 5.6% of the Nepalese population at over 1.3 million in 2001, increasing to 1,539,830 as of the 2011 census. The Tamang people are concentrated in the central hilly region of Nepal. Indian Tamangs are found in significant numbers in the state of Sikkim and the districts of Darjeeling and Kalimpong in West Bengal state. Bhutanese Tamangs are native to various districts in the southern foothills of the Kingdom of Bhutan. Such districts include the Tsirang District, the Dagana District, the Samtse District, the Chukha District, the Sarpang District and the Samdrup Jongkhar District. Tamang language is the fifth most-spoken language in Nepal.
Tamang may have been derived from the word Tamang, where Ta means "horse" and Mak means "warrior" in Tibetan. However, there are no written documentations of Horse Riders. Some scientific research claims the Tamangs have Prehistoric and Genetic roots.
The Tamangs, who have lived from hills outside the Kathmandu Valley to the southern slope of Langtang, Ganesh, Jugal himal and Rolwaling probably since pre-historic time, have been mentioned in various Nepalese and colonial historical records under a variety of names, such as Bhote, Lama, Murmi, Sain some of which terms erroneously conflate the Tamangs with Uighurs. Meanwhile, the Tibetans called them Rongpa.
Various Gorkha rulers led campaigns against the Indigenous Tamangs, The Gorkha Vamsavali provides details of battles with the Bhotyas of a variety of principalities between 1806 and 1862. In 1739, a ruler named Ghale-Botya attacked Narabhupal Shah as he was marching towards Nuwakot, and Narabhupal Shah also fought several battles against Golma Ghale. In 1762, Prithvi Narayan Shah attacked the Tamangs in Temal, the Tamang cultural heartland. Tamang oral history tells how the local chief, Rinjen Dorje, was killed by the Gorkhas, In the fight time gorkhali forces had hidden their weapons in the sand on the Sunkoshi riverbank.
