Buddhist tantric literature refers to the vast and varied literature of the Vajrayāna Buddhist traditions. The earliest of these works are a genre of Indian Buddhist tantric scriptures, variously named Tantras, Sūtras and Kalpas, which were composed from the 7th century CE onwards. They are followed by later tantric commentaries, original compositions by Vajrayana authors, sādhanas, ritual manuals, collections of tantric songs (dohās) odes (stotra), or hymns, and other related works. Tantric Buddhist literature survives in various languages, including Sanskrit, Tibetan, and Chinese. Most Indian sources were composed in Sanskrit, but numerous tantric works were also composed in other languages like Tibetan and Chinese.

Vajrayāna, also known as Mantrayāna, Mantranāya, Guhyamantrayāna, Tantrayāna, Tantric Buddhism, and Esoteric Buddhism, is a Buddhist tradition of tantric practice that developed in the Indian subcontinent and spread to Tibet, Nepal, other Himalayan states, East Asia, and Mongolia.
