Route 37 is a north–south state highway in Connecticut running for 18.66 miles (30.03 km) from Route 39 in Danbury, through New Fairfield, to U.S. Route 7 in New Milford. The northernmost section between the town centers of Sherman and New Milford was once part of an early toll road known as the New Milford and Sherman Turnpike chartered in 1818.

Route 37 begins at an intersection with Route 39 and Route 53 in downtown Danbury, where one can also access I-84 (Exit 6). It heads northeast as North Street, crossing under I-84 at Exit 7 with access to the eastbound direction only. North of I-84, the road continues as Padanaram Road for about 1.3 miles (2.1 km) then shifts to Pembroke Road. Route 37 crosses into the town of New Fairfield after another 2.1 miles (3.4 km), as it skirts the banks of the Margerie Lake Reservoir. Route 37 intersects with Route 39 for a second time in New Fairfield center, where the road name changes to Sherman-New Fairfield Road. Route 37 continues through the northwest section of New Fairfield. Along the way it intersects with Patterson Road, an unsigned state highway known as State Road 850, which connects to Putnam County Road 68 in New York state. Route 37 then enters the town of Sherman as Greenwoods Hill Road and passes through the Pootatuck State Forest. About 4.5 miles (7.2 km) north of the town line, Route 37 meets Route 39 for the third time in Sherman center. After overlapping Route 39 for about 0.4 miles (0.64 km), the two routes split, with Route 37 heading east (as Barnes Hill Road) and Route 39 heading north. Route 37 crosses into the town of New Milford after another 1.4 miles (2.3 km). Route 37 ends at U.S. Route 7 in New Milford at the banks of the Housatonic River about 1.6 miles (2.6 km) later.
