Route 25 is a 28.59-mile (46.01 km), primary state highway connecting the city of Bridgeport and the town of Brookfield in the U.S. state of Connecticut. Route 25 is a six-lane freeway from Bridgeport to northern Trumbull and a two-lane surface road the rest of the way to Brookfield.

Route 25 was originally laid out as a toll road known as the Bridgeport and Newtown Turnpike in 1801. The Route 25 designation was assigned in 1932 to the turnpike alignment and additionally extended through New Milford all the way to Torrington. The route was cut back to its modern northern terminus in Brookfield in 1974, with U.S. Route 202 taking over the old alignment. The Bridgeport-Newtown corridor had been planned as an expressway since the 1950s. The modern Route 25 expressway was fully open by 1982.

Route 25 begins at an interchange with Interstate 95 in Bridgeport. For the first 3.8 miles (6.1 km) of the route, it is co-signed with the Route 8 freeway. After the split with Route 8, it continues as its own freeway through the town of Trumbull for another 6.1 miles (9.8 km), providing partial access to the Merritt Parkway (Route 15) along its path through the town. The freeway portion ends at the junction with Route 111 on the northern edge of town.
