The Hamsa Upanishad (Sanskrit: हंसोपनिषद्) is a Sanskrit text and a minor Upanishad of Hinduism. It is classified as one of the twenty Yoga Upanishads, and attached to the Shukla Yajurveda. The text or parts of the text is a relatively late origin, probably from the 2nd-millennium of the common era, but written before early 17th-century, because Dara Shikoh included it in the Persian translation of the Upanishads as Oupanekhat, spelling it as Hensnad (Hamsa-nada).
