The Montauk Branch is a rail line owned and operated by the Long Island Rail Road in the U.S. state of New York. The line runs the length of Long Island, 115 miles (185 km) from Long Island City to Montauk. However, in LIRR maps and schedules for public use, the term Montauk Branch refers to the line east of Babylon; service from Jamaica to Babylon is covered by separate Babylon Branch schedules, while the line west of Jamaica is currently unused for passenger service. A select number of Montauk Branch trains operate via the Main Line during peak hours.

The Richmond Hill station is a closed station on the Montauk Branch of the Long Island Rail Road in the Richmond Hill neighborhood of Queens in New York City. The station is located at Myrtle Avenue and cuts diagonally from the intersection of Jamaica Avenue and Lefferts Boulevard through to Hillside Avenue. The station has two tracks and an island platform. Richmond Hill was the only station on the Lower Montauk Branch that was elevated with a high-level platform for passengers to wait for trains; the others were at ground level, with low-level platforms.
