Alex Grey (born November 29, 1953) is an American visual artist, author, teacher, and Vajrayana practitioner known for creating spiritual and psychedelic artwork such as his 21-painting Sacred Mirrors series.

He is also on the board of advisors for the Center for Cognitive Liberty and Ethics, and is the Chair of Wisdom University's Sacred Art Department.

He and his wife Allyson Grey are the co-founders of The Chapel of Sacred Mirrors (CoSM), a non-profit organization in Wappingers Falls, New York.

[1] Mending the Heart Net, an interactive installation artwork by Alex and Allyson Grey, was displayed at Baltimore's American Visionary Art Museum in 1998–99 as part of the exhibition "Love: Error and Eros".

[9] That same year, Grey was noticed by guitarist Adam Jones of the progressive metal band Tool, who later featured his artwork on their albums Lateralus and 10,000 Days.

[7] Illustrations created by Grey have been selected to appear on albums for musical groups such as the Beastie Boys and Nirvana,[3] as well as Meshuggah[10] and The String Cheese Incident.

[4] In the 2012 book Psychedelia, author Patrick Lundborg credits Grey as "the leading psychedelic artist of today, and also one of the foremost proponents of Visionary Art as a style.

Grey's project The Chapel of Sacred Mirrors (CoSM) first opened to the public in Chelsea, New York in 2004 and drew visionary and psychedelic art fans to the site for four years until its closure in December 2008.

The Sacred Mirrors, a life-sized series of 21 paintings, took 10 years to complete, and examines in detail the physical and metaphysical anatomy of the individual.

Grey's work incorporates many religious symbols, including auras, chakras, and icons with geometric shapes and tessellations in natural, industrial, and multicultural situations.

Every bone, organ and vein is detailed in refulgent color; objects and space are knitted together in dense, decorative linear webs.

The book included essays on the significance of Grey's work by Ken Wilber, and by New York art critic, Carlo McCormick.

[20] The book traces the evolution of human consciousness through art history, explores the role of an artist's intention and conscience, and reflects on the creative process as a spiritual path.

Grey and the Chapel of Sacred Mirrors gallery in New York City were featured in the 2006 documentary CoSM The Movie, directed by Nick Krasnic.

[24] Grey appeared in the 2006 film Entheogen: Awakening the Divine Within, a documentary about rediscovering an enchanted cosmos in the modern world.

The Viking Youth Power Hour interviewed Alex and Allyson Grey about the role of sacred art, the holy shenanigans of Burning Man, and the development of his process.
