The Connecticut Valley Railroad was a railroad in the state of Connecticut founded in 1868. The company built a line along the Connecticut River between Hartford and Old Saybrook, which opened in 1871. It was reorganized as the Hartford and Connecticut Valley Railroad in 1880, and leased by the New York, New Haven and Hartford Railroad in 1887. Following partial abandonments by the New Haven Railroad and successor Penn Central Transportation Company between 1968 and 1972, the line south of Middletown was revived as the Valley Railroad, a heritage railroad, while the portion in Middletown and northward saw operation by several freight railroads. As of 2022, the Providence and Worcester Railroad and Connecticut Southern Railroad both operate portions of the former Connecticut Valley Railroad.
