Pine River Institute is a Canadian live-in treatment centre and outdoor leadership program for adolescents. Its official site describes the program as serving youth ages 13 to 19 who struggle with addictive behaviours and other mental-health issues, combining residential treatment, outdoor leadership, therapy, family work, and a fully accredited education program near Shelburne, Ontario (Pine River Institute).

The program opened in 2006. Pine River describes itself as the only program of its kind in Canada, and Ontario government materials identify it as a not-for-profit facility for youth ages 13 to 19 with addictive behaviours and often co-occurring mental-health challenges (program page, Ontario Newsroom).

ConnexOntario lists Pine River's Mulmur/Shelburne campus as a residential treatment program for youth with addiction and co-occurring mental-health needs (ConnexOntario).
