Barnwood House Hospital (1860–1968) was a private mental hospital in Barnwood, Gloucester, England. It was founded by the Gloucester Asylum Trust in 1860 as Barnwood House Institution and later became known as Barnwood House Hospital. The hospital catered for well-to-do patients, with reduced terms for those in financial difficulties. It was popular with the military and clergy, and once counted an Archbishop amongst its patients. During the late nineteenth century Barnwood House flourished under superintendent Frederick Needham, making a healthy profit and receiving praise from the Commissioners in Lunacy. Even the sewerage system was held up as a model of good asylum practice.
