Religions practiced in Tibet encompass Tibetan Buddhism, Bon and folk religion, plus Islam and Christianity. At present, there are some 1,700 monasteries and nunneries of Tibetan Buddhism in the region, with 46,000 resident monks and nuns; 88 monasteries of the Bon religion, with some 3,000 resident monks, 93 Living Buddhas and over 130,000 religious followers; four mosques, with some 3,000 followers; and one Christian church, with over 700 worshippers.

The social influence of these religions varies with the regions. The influence of folk religion can be found only in the remote areas. As a result, it is very often ignored in Tibet as, unlike Tibetan Buddhism, the Bon religion, Islam and Christianity, it lacks theory, special venues for rituals and religious organizations. Tibetan Buddhism and the Bon religion are opposing faiths, although they have long exerted influence on each other. Thus parts of the Tibetan Buddhism can be found in the tenets of the Bon, and vice versa. Both have absorbed the cream of the folk religion, such as worship of certain folk spirits. Islam and Christianity are small in the number of followers and influence in Tibet. They are practiced only in a limited area. However, they do exist and live harmoniously with Tibetan Buddhism and the Bon religion. Folk religion is still influential among the Tibetan folks.
