Route 219 is a state highway in northern Connecticut, running from New Hartford to Granby.

Route 219 begins at an intersection with US 202 in southern New Hartford and heads north, northeast, and east before crossing the West Branch Farmington River at the town center.

In Barkhamsted, it continues north along the east shore of the McDonough Reservoir to its northern end, then turns northeast.

In 1955, a section of Steele Road in New Hartford that had been town-maintained was added to the state highway system, completing state-maintenance of the route.

Later in the same year, the Cottage Street Bridge was destroyed in a flood, temporarily severing the route.
