Drikung Kagyu or Drigung Kagyu (Wylie: 'bri-gung bka'-brgyud) is one of the eight "minor" lineages of the Kagyu school of Tibetan Buddhism. "Major" here refers to those Kagyu lineages founded by the immediate disciples of Gampopa (1079-1153) while "minor" refers to all the lineages founded by disciples of Phagmo Drupa (1110-1170), the main disciple of Gampopa.
Like with all other Kagyu lineages, origins of Drikung Kagyu can be traced back to the Great Indian Master Tilopa who passed on his teachings to Mahasiddha Naropa who lived around 10th and 11th century. The founder of the Drikung Kagyu lineage was Jigten Sumgön (1143-1217) of the Kyura clan, who was the disciple of Phagmo Drupa. According to historical account from the time, Jigten Sumgön's teachings attracted more than 100,000 people at a time, with the highest number of attendance recorded at 130,000.
Several sub-schools branched off from the Drikung Kagyu including the Lhapa or Lhanangpa Kagyu, founded by Nö Lhanangpa (Wylie: gnyos lha nang pa, 1164–1224) who came to Bhutan in 1194. This school was at one time important in Western Bhutan, particularly in the Thimphu and Paro regions, where they were rivals of the Drukpa Kagyu. The Lhapa first came into conflict with the early Drukpa teacher, Phajo Drugom Zhigpo (b. 12th century) and finally with Ngawang Namgyal (1594–1651). In 1640 the remaining followers of the Lhapa Kagyu were expelled from Bhutan together with the Nenyingpa followers as both had sided with the attacking Tsangpa forces against the Drukpa during their three invasions of Bhutan and continued to refuse to acknowledge the authority of the Shabdrung.
The first and main Drikung Kagyu monastery is Drikung Thil Monastery, founded in 1179 by Jigten Sumgön approximately 150 kilometers northeast of Lhasa.
