The New Haven and Derby Railroad (NH&D) was a railroad that connected the city of New Haven, Connecticut, with the town of Derby. The railroad was built between 1868 and 1871, when it began operations. The company was created by the city of New Haven, which owned it until 1889 when it was sold to the Housatonic Railroad. The Housatonic in turn was purchased by the New York, New Haven and Hartford Railroad in 1892. Passenger service existed between New Haven and Derby Junction until 1925 when it was discontinued.

The majority of the line was abandoned by the New Haven Railroad between 1939 and 1941. As of 2022, 3 miles (4.8 km) of track between Derby and Ansonia are the only remaining portion of the New Haven and Derby Railroad in service.
