125th Street (formerly Manhattan Street), is a local station on the IRT Broadway–Seventh Avenue Line of the New York City Subway. Located at the intersection of 125th Street and Broadway, where Morningside Heights meets Harlem in an area known as Manhattanville, it is served by the 1 train at all times. The station is the southernmost elevated station on the line, the southernmost one in Manhattan, and the only one south of Dyckman Street.

Operation of the first subway began on October 27, 1904, with the opening of the original 28 stations of the New York City Subway from City Hall to 145th Street on the West Side Branch including the 125th Street station.

In 1948, platforms on the IRT Broadway–Seventh Avenue Line from 103rd Street to 238th Street were lengthened to 514 feet to allow full ten-car express trains to platform. Previously the stations could only platform six car local trains. The platform extensions were opened in stages. The platform extensions at 125th Street opened on June 11, 1948.

This is the only station on the short elevated Manhattan Valley Viaduct, which bridges Manhattanville from 122nd to 135th Streets and has been on the National Register of Historic Places since 1983. This viaduct allows the trains to remain relatively level and avoid steep grades while traversing the valley. The overall length is 2,174 feet (663 m) and the steel arch across 125th Street is 168.5 feet (51.4 m) long.
