The Narragansett Pier Railroad (reporting mark NAP) was a railroad in southern Rhode Island, running 8 miles (13 km) from West Kingston to Narragansett Pier. It was built by the Hazard Family of Rhode Island to connect their textile mills in Peace Dale and Wakefield to the New York, Providence and Boston Railroad at Kingston Station as well as to ocean-going steamboats at Narragansett Pier. Passenger service ran on the line from 1876 to 1952; the line continued freight operation as a Class III railroad until 1981. Most of the right-of-way has been converted to the William C. O'Neill Bike Path.
