Ardsley-on-Hudson station is a commuter rail stop on the Metro-North Railroad's Hudson Line, located in the Ardsley Park area of Irvington, New York. It serves both the neighborhood and the northern part of the village of Dobbs Ferry; the main campus of Mercy College is within walking distance of the station. A common misconception is that the Ardsley-on-Hudson station serves the similarly named village of Ardsley, which is located about 2.5 miles (4.0 km) east, and was once served by the discontinued Putnam Division line, which ceased passenger service in 1958.
