From Wikipedia:

Analytical psychology (sometimes analytic psychology), also called Jungian psychology, is a school of psychotherapy which originated in the ideas of Carl Jung, a Swiss psychiatrist. It emphasizes the importance of the individual psyche and the personal quest for wholeness.[1]

Important concepts in Jung’s system are individuationsymbols, the personal unconscious, the collective unconsciousarchetypescomplexesthe personathe shadowthe anima and animus, and the self.

Jung’s theories have been investigated and elaborated by Toni WolffMarie-Louise von FranzJolande JacobiAniela JafféErich NeumannJames HillmanJordan Peterson, and Anthony Stevens.

Analytical psychology is distinct from psychoanalysis, which is a psychotherapeutic system created by Sigmund Freud.
