Route 177 is a state highway in central Connecticut, running from Plainville to Canton.

Route 177 begins as Town Line Road at an intersection with Route 10 in Plainville, just north of the Southington town line. It heads west for 0.2 miles (0.32 km) then turns north onto South Washington Street. From this intersection, South Washington Street continues one way southbound into Southington as Birch Street (SR 532), and ends at Route 10. Route 177 continues north along South Washington Street to the town center of Plainville, where it intersects with Route 372 and becomes North Washington Street. After crossing the Pequabuck River, it soon has a junction with Route 72, connecting with it via a partial interchange allowing access to and from points east. North of the intersection, the road becomes Unionville Avenue as it continues north into the town of Farmington.
