Yogācāra (Sanskrit; literally: "yoga practice"; "one whose practice is yoga") is an influential school of Buddhist philosophy and psychology emphasizing phenomenology and (some argue) ontology through the interior lens of meditative and yogic practices. It developed within Indian Mahāyāna Buddhism in about the 4th century CE.

Yogācāra discourse explains how our human experience is constructed by mind.

Yogācāra is also transliterated (using standard English alphabet) as "yogachara". Another name for the school is Vijñānavāda (Sanskrit). Vāda means "doctrine" and "way"; vijñāna means "consciousness" and "discernment."

The Yogācāra, along with the Mādhyamaka, is one of the two principal philosophical schools of Nepalese and Indian Mahāyāna Buddhism.

Masaaki (2005) states: "[a]ccording to the Saṃdhinirmocana Sūtra, the first Yogācāra text, the Buddha set the 'wheel of the doctrine' (Dharmacakra) in motion three times." Hence, the Saṃdhinirmocana Sūtra, as the doctrinal trailblazer of Yogācāra, inaugurated the paradigm of the three turnings of the wheel of Dharma, with its own tenets in the "third turning". The Yogācāra texts are generally considered part of the third turning along with the relevant sutra. Moreover, Yogācāra discourse surveys and synthesizes all three turnings.

Dan Lusthaus, a graduate of Temple University's Department of Religion, is a specialist in Yogācāra Buddhism. The author of several articles and books on the topic, Lusthaus has taught at UCLA, Florida State University, the University of Missouri, and in the Spring of 2005 he was a professor at Boston University.

Lusthaus also collaborated with Heng-ching Shih in the translation of Kuiji's (K'uei-chi) commentary on the Heart Sutra with the Numata translation project. Lusthaus is an editor for the DDB, in the area of Indian/East Asian Yogācāra/Tathāgatagarbha. He contributed the contents of his catalogue of the major Yogācāra translations of Xuanzang to the DDB, as well as a number of other terms related to the Cheng Weishi Lun and Yogācārabhūmi-śāstra.
