South London and Maudsley NHS Foundation Trust

South London and Maudsley NHS Foundation Trust, also known as SLaM, is an NHS foundation trust based in London, England, which specialises in mental health. It comprises four psychiatric hospitals (Bethlem Royal Hospital, Lambeth Hospital and the Maudsley Hospital), the Ladywell Unit based at University Hospital Lewisham, and over 100 community sites and 300 clinical teams. SLaM forms part of the institutions that make up King's Health Partners, an academic health science centre.

In its most recent inspection of the Trust, the CQC gave SLaM a 'good' rating overall, but a 'requires improvement' rating in area of safety. In 2019, Southwark Coroner's Court ruled that SLaM was guilty of "neglect and serious failures" in relation to the death of a patient in 2018. In 2020, a further investigation into the Trust's conduct was opened following the death of a patient in its care.
