Millhaven Institution (French: Établissement de Millhaven) is a maximum security prison located in Bath, Ontario. Approximately 500 inmates are incarcerated at Millhaven.

Opened in 1971, Millhaven was originally built to replace Ontario's other aging maximum security prison, Kingston Penitentiary in Kingston Ontario. A riot at Kingston Penitentiary forced Millhaven to open prematurely. During the period of 1977–1984, a Special Handling Unit (SHU) operated at Millhaven, alongside its general maximum-security population. A new Canada-wide Special Handling Unit was subsequently opened in Sainte-Anne-des-Plaines Quebec, and the Millhaven SHU was closed.

Millhaven also housed the federal inmate intake and assessment unit for the Ontario region. (Millhaven Assessment Unit or MAU until 2013 when the assessment unit was moved to Joyceville High Medium Institute (JAU) in order to facilitate the closing of Kingston Pen). Federal parole violators were returned to MAU (from whatever Ontario region they were arrested) to appear in front of the National Parole Board for disposition. Millhaven is one of two identically designed maximum security institutions in Canada. The other is located at Archambault Institution, Sainte-Anne-des-Plaines, Quebec.

Also located on same property is Bath Institution, a medium security facility located along the shores of Lake Ontario. Opened in 1972, it houses 340 inmates.

Millhaven consists of three main living units, a segregation unit and a hospital wing. There are approximately 120 men per unit. Units have two levels. Ranges are double-sided and have hydraulically locking metal doors (See video in "External Links" section), housing two inmates per cell. The ranges/cells are designated by alphanumeric code (i.e. B1, H2 etc.).

Main living units are designated by Alpha codes:

A Unit = Federal Intake and Assessment Unit - Ontario region (MAU) (ranges B, C, & D)
