Ratnamegha Sutra, or the Jewel Cloud Sutra (Skt. Ratnamegha-sūtra; Tib. དཀོན་མཆོག་སྤྲིན་གྱི་མདོ།, Wyl. dkon mchog sprin gyi mdo) — an important sutra for the exposition of shamatha and vipashyana in the Tibetan tradition. It is considered to be the first sutra translated into Tibetan by Thonmi Sambhota.
Although the Sanskrit of many passages is preserved in the excerpts cited in the Indian shastra literature, the Ratnamegha Sutra as a whole is no longer extant in Sanskrit.
Four versions of the sutra are, however, available in Chinese translation.
