The Red Gaurs (Thai: กระทิงแดง "Krathing Daeng") were an extreme right-wing paramilitary organization active in Thailand during the 1970s. The Red Gaurs played a key role in the 6 October 1976 massacre of students and activists at Thammasat University. The organization derives its name from the gaur (/ɡaʊər/, "Bos gaurus"), also called the Indian bison, the largest extant bovine. The gaur is native to the Indian subcontinent and Southeast Asia.
