Bon or Bön, also known as Yungdrung Bon, is the indigenous Tibetan religion which shares many similarities and influences with Tibetan Buddhism. It initially developed in the tenth and eleventh centuries but retains elements from earlier Tibetan religious traditions. Bon is a significant minority religion in Tibet, especially in the east, as well as in the surrounding Himalayan regions.

The main religion in Tibet has been Buddhism since its outspread in the 8th century AD. As of 2022 the historical region of Tibet is mostly comprised in the Tibet Autonomous Region (TAR) of China and partly in the Chinese provinces of Qinghai and Sichuan. Before the arrival of Buddhism, the main religion among Tibetans was an indigenous shamanic and animistic religion, Bon, which would later influence the formation of Tibetan Buddhism and still attracts the allegiance of a sizeable minority of Tibetans.
