Route 115 is a Connecticut state highway in the Lower Naugatuck River Valley area, running from Route 34 in Derby to Route 67 in Seymour. The road runs along the east bank of the lower Naugatuck River.

Route 115 begins as Derby Avenue in Derby, continuing north from Route 34, which turns west to cross the Naugatuck River. It enters the city of Ansonia after 0.8 miles (1.3 km), becoming Main Street. At the Derby-Ansonia line, Route 115 meets the western end of Route 243 (for Woodbridge and New Haven) and its continuation across the Naugatuck River (Division Street), which provides access to shopping areas as well as the Route 8 expressway. Route 115 continues north into Ansonia center, passing by the Ansonia station of the Waterbury Branch of the Metro-North Railroad. It then meets the east end of Route 334 (Maple Avenue) and proceeds north as North Main Street, entering the town of Seymour about 1.2 miles (1.9 km) later. In Seymour, it becomes South Main Street, meeting and briefly overlapping Route 313 (for New Haven) then ending 0.2 miles (0.32 km) later at an intersection with Route 67 near the Seymour railroad station.
