Kei Ito (伊東 慧, Itō Kei, born 20 February 1991) is a Japanese visual artist working primarily with installation art and experimental photography currently based in the United States.

Ito's work addresses issues of deep intergenerational loss and connections as he explores the materiality and experimental processes of photography, visualizing the invisible: radiation, memory and life/death.

Ito's work, fundamentally rooted in the trauma and legacy passed down from his late grandfather ( Takeshi Ito )—a survivor of the atomic bombing of Hiroshima—, meditates on the complexity of his identity and heritage through examining the past and current threats of nuclear disaster and his present status as a US immigrant.

Many of Ito's artworks transformed both art and non-art spaces into temporal monuments that became platforms for the audience to explore social issues and the memorials dedicated to the losses suffered from the consequences of those issues.

Group exhibitions of note include: the Norton Museum of Art, West Palm Beach, FL; Ethan Cohen KuBe, NY; the Walters Museum of Art, Baltimore, MD; Museum of Contemporary Photography, Chicago, IL; California Institute of Integral Studies, San Francisco, CA; and PH21 Gallery in Budapest, Hungary.
