The Paterson and Ramapo Railroad was a railroad that operated mostly in New Jersey, connecting the city of and Paterson, New Jersey with Suffern, New York, just across the state line. The railroad was chartered in 1841 and construction began in 1847. It was created to form a connection between the Paterson and Hudson River Railroad, one of the earliest railroads in the United States, and the Erie Railroad in Suffern. The two Paterson railroads provided a shorter route from Suffern to New York City than did the New York and Erie Railroad.
