Stony Mountain Institution is a federal multi-security complex located in the Rural Municipality of Rockwood immediately adjacent to the community of Stony Mountain, Manitoba, about 24 km (15 mi) from Winnipeg.
The Institution (medium-security) began operations in 1877, making it the oldest running federal prison in Canada following the closure of Ontario's Kingston Penitentiary on 30 September 2013. Immediately adjacent to Stony Mountain Institution is the Rockwood Institution, a minimum-security facility established in 1962. The newest addition to Stony Mountain, the maximum-security unit, opened in 2014.
