Daniel "Dan" Graham is an American artist, writer, and curator.

Graham grew up in New Jersey. In 1964 he began directing the John Daniels Gallery in New York, where he put on Sol LeWitt's first one-man show, and in groups shows, exhibited works of Donald Judd, Dan Flavin and Robert Smithson. Like these artists, Graham considered himself a writer-artist, publishing essays and reviews on rock music, Dwight D. Eisenhower's paintings, and Dean Martin's television show. His earliest work dealt with the magazine page, predating but often associated with Conceptual art. His work often focuses on cultural phenomena, and incorporates photography, video, performance art, glass and mirror structures. He lives and works in New York.
