The Tavistock and Portman NHS Foundation Trust is a specialist mental health trust based in north London. The Trust specialises in talking therapies. The education and training department caters for 2,000 students a year from the United Kingdom and abroad. The Trust is based at the Tavistock Centre in Swiss Cottage. The founding organisation was the Tavistock institute of medical psychology founded in 1920 by Dr. Hugh Crichton-Miller. The Tavistock and Portman NHS Trust was formed in 1994, when the Tavistock Clinic merged with the neighbouring Portman Clinic in Fitzjohn's Avenue.

It has developed as a centre of excellence for psychoanalysis within the NHS since being included at its founding in 1948.

Following its foundation the Tavistock Clinic developed a focus on preventive psychiatry, expertise in group relations – including army officer selection – social psychiatry, and action research. There was an openness to different streams of research and thought as, for instance, the famous series of lectures given by the Swiss psychiatrist and one time collaborator of Sigmund Freud, Dr. Carl Jung, which were attended by doctors, churchmen and members of the public, including H.
