Group psychotherapy or group therapy is a form of psychotherapy in which one or more therapists treat a small group of clients together as a group. The term can legitimately refer to any form of psychotherapy when delivered in a group format, including cognitive behavioural therapy or interpersonal therapy, but it is usually applied to psychodynamic group therapy where the group context and group process is explicitly utilised as a mechanism of change by developing, exploring and examining interpersonal relationships within the group.

The broader concept of group therapy can be taken to include any helping process that takes place in a group, including support groups, skills training groups (such as anger management, mindfulness, relaxation training or social skills training), and psychoeducation groups. The differences between psychodynamic groups, activity groups, support groups, problem-solving and psycoeducational groups have been discussed by psychiatrist Charles Montgomery. Other, more specialised forms of group therapy would include non-verbal expressive therapies such as art therapy, dance therapy, or music therapy.

The founders of group psychotherapy in the USA were Joseph H. Pratt, Trigant Burrow and Paul Schilder. All three of them were active and working at the East Coast in the first half of the 20th century. After World War II, group psychotherapy was further developed by Jacob L. Moreno, Samuel Slavson, Hyman Spotnitz, Irvin Yalom, and Lou Ormont. Yalom's approach to group therapy has been very influential not only in the USA but across the world.
