Buddhism is a small minority religion in Bulgaria, with about a thousand practitioners. The Vietnamese community in Bulgaria traditionally practices Mahayana Buddhism alongside Ancestor Worship, but the population of this community, which mostly hails from North Vietnam, has declined from tens of thousands before 1990 to around 1,000 now. Some Buddhist believers in Bulgaria are of Chinese descent. A small number of native Bulgarians are converts to Theravada and Tibetan Buddhism.
