Raymond Edward "Ray" Johnson (October 16, 1927 – January 13, 1995) was an American artist. Known primarily as a collagist and correspondence artist, he was a seminal figure in the history of Neo-Dada and early Pop art and was described as "New York's most famous unknown artist". Johnson also staged and participated in early performance art events as the founder of a far-ranging mail art network – the New York Correspondence School – which picked up momentum in the 1960s and is still active today. He is occasionally associated with members of the Fluxus movement but was never a member. He lived in New York City from 1949 to 1968, when he moved to a small town in Long Island and remained there until his suicide.
