St David's Hospital (Welsh: Ysbyty Dewi Sant) is a health facility in Canton, Cardiff, Wales.

[2] Because of the growing population of the area, in 1862 child inmates were relocated to the Ely Industrial Schools.

This fell into disrepair and was the target of vandalism, but in 2002 it was refurbished and converted into apartments.

[7] A modern facility, located to the rear of the old hospital, was commissioned under a Private Finance Initiative contract in 1999.

[10] Facilities included 100 beds, initially for mental health patients (transferred from Royal Hamadryad Hospital) and the elderly (from Lansdowne Hospital) but also including children's services, therapies and dental services.
