Elliott Jaques (1917 - 2003) was a Canadian psychologist. He developed the notion of requisite organization, running counter to many others in the field of organizational development.

Jaques was educated at University of Toronto and studied medicine at Johns Hopkins University before receiving his Ph.D in social relations from Harvard University. During World War II, he moved to England where he remained after the war, studying under Austrian psychotherapist Melanie Klein. He was a founder, in 1946, of the Tavistock Institute of Human Relations.

The concept of the mid-life crisis is attributed to Jaques.
