In Tibetan Buddhist and Indian Buddhist traditions, Shambhala (also spelled Shambala or Shamballa; Tibetan: བདེ་འབྱུང་; Wylie: bde 'byung, pron. De-jung) is a mythical kingdom hidden somewhere in Inner Asia. It is mentioned in various ancient texts, including the Kalachakra Tantra and the ancient texts of the Zhang Zhung culture which predated Tibetan Buddhism in western Tibet. The Bön scriptures speak of a closely related land called Olmolungring.

Whatever its historical basis, Shambhala gradually came to be seen as a Buddhist Pure Land, a fabulous kingdom whose reality is visionary or spiritual as much as physical or geographic. It was in this form that the Shambhala myth reached the West, where it influenced non-Buddhist as well as Buddhist spiritual seekers — and, to some extent, popular culture in general.

Sambhala (this is the form found in the earliest Sanskrit manuscripts of Kalachakra texts; the Tibetans usually transliterated this as "Shambhala"; Tib. bde 'byung) is a Sanskrit term of uncertain derivation. Commonly it is understood to be a "place of peace/tranquility/happiness". Shakyamuni Buddha is said to have taught the Kalachakra tantra on request of King Suchandra of Shambhala; the teachings are also said to be preserved there. Shambhala is believed to be a society where all the inhabitants are enlightened, actually a Buddhist Pure Land, centered by a capital city called Kalapa.
