Palo Alto University (PAU) is a private university in Palo Alto, California that focuses on psychology. It was founded in 1975 as the Pacific Graduate School of Psychology.

Palo Alto University offers two undergraduate degree programs (Bachelor of Science in Psychology and Social Action and Bachelor of Science in Business Psychology) and four graduate programs: a Ph.D. in Clinical Psychology, a Psy.D. in Clinical Psychology as part of a consortium with Stanford University, and two master's degree programs: an M.A. in Counseling and an M.S. in Psychology. PAU subscribes to the practitioner-scientist training model, a variation of the Boulder scientist-practitioner model, which emphasizes clinical practice along with scientific training.

PAU has an interconnected relationship with Stanford University and the Stanford University School of Medicine. PAU maintains its doctoral program in conjunction with Stanford University, often employs its students in Stanford research laboratories, and houses faculty members who teach at both institutions. The chair of the Stanford Department of Psychiatry holds a membership on the PAU board of trustees.
