Route 69 is a primary north–south state highway in the U.S. state of Connecticut connecting the city of New Haven to the city of Bristol in the western part of Greater Hartford, passing through Greater Waterbury along the way.

Past the Parkway, the road becomes known as Litchfield Turnpike and heads northward along the western side of West Rock.

It used the southernmost portion of the old Litchfield Turnpike (local name for the Straits Turnpike) from the Amity section of New Haven to Bethany, then former town roads from Bethany to Prospect (Carrington Road and New Haven Road), and then former State Highway 348 from Prospect to East Main Street (then Route 14) in Waterbury.

The section from Waterbury to Bristol (former State Highway 172) was renumbered to Route 119 in 1932.

At the same time, the route in Waterbury was shifted slightly east (from Wolcott Street to Woodtick Road) for better through traffic flow.
