Riccartsbar Hospital was a mental health facility in Paisley, Renfrewshire, Scotland.
The hospital, which was designed by John Honeyman, opened as the Paisley District Asylum in June 1876. The hospital went into a period of decline and, after patients had been transferred to Dykebar Hospital, Riccartsbar Hospital closed in 1975. The buildings were subsequently demolished to make way for the Royal Alexandra Hospital.
