Route 151 is a Connecticut state highway in the Connecticut River valley running from East Haddam via Moodus to the village of Cobalt in East Hampton.

Route 151 begins as Town Street at an intersection with Route 82 east of the town center of East Haddam. The road heads north for 2.7 miles (4.3 km) through the village of Little Haddam up to the village of Moodus. In Moodus, the road turns west to briefly overlap southbound Route 149 along a 0.3-mile (0.48 km) wrong way concurrency (as Moodus-Leesville Road).

Immediately after Route 149 splits off to the south, Route 151 crosses the Moodus River and then continues west for another mile. It then turns north along Leesville Road as it heads towards the Haddam town line. The southward continuation of Leesville Road connects with Route 149 and is an unsigned state highway known as State Road 609. After crossing the Salmon River into Haddam, the road becomes Moodus Road. After about 0.4 miles (0.64 km), Route 196 splits off to the north (towards East Hampton center), while Route 151 heads west, also crossing into the town of East Hampton about 0.9 miles (1.4 km) later.
