South West London and St George's Mental Health NHS Trust is an NHS trust that provides mental health services for adults, older people, children and adolescents living in the London boroughs of Kingston, Merton, Richmond, Sutton and Wandsworth.

In 2019, the Care Quality Commission inspection report rated the hospital as "Good".

It plans to reduce inpatient beds across south-west London by 10 percent before 2018, and treat more people in the community.

It was named by the Health Service Journal as one of the top hundred NHS trusts to work for in 2015.
