The Clarke Institute of Psychiatry was the name of a psychiatric hospital in Toronto, Ontario.
Much of their work focuses on forensic psychology, sex addiction, drug addiction, and research designed to shape public policy. It is named after Charles Kirk Clarke, a pioneer in mental health in Canada.
In 1998, the Clarke Institute merged with several other Ontario institutions to form the Centre for Addiction and Mental Health (CAMH), and the facility is now called the CAMH Clarke Campus.
