Consultation–liaison psychiatry (C-L psychiatry or liaison psychiatry) is a subspecialty of psychiatry concerned with the assessment and treatment of psychiatric disorders and psychological distress in patients with medical, surgical or neurological conditions, usually in general hospitals and other medical settings. It operates at the interface between general medicine and psychiatry and is closely related to psychosomatic medicine, health psychology and neuropsychiatry.

Modern C-L psychiatry is commonly described within the biopsychosocial model proposed by George L. Engel, which emphasises the interaction of biological, psychological and social factors in health and disease.
