The New York City Subway is a rapid transit system that serves four of the five boroughs of New York City in the U.S. state of New York: the Bronx, Brooklyn, Manhattan, and Queens. Its predecessors—the Interborough Rapid Transit Company (IRT), the Brooklyn–Manhattan Transit Corporation (BMT), and the Independent Subway System (IND)—were consolidated in 1940. Since then, many New York City Subway stations have been permanently closed, either entirely (9 of them) or in part (24 of them).

The largest number of closed New York City Subway stations consist of stations on abandoned and demolished elevated lines that were once operated by the IRT and the BMT, both of which were privately held companies. After their takeover by the City of New York (the IND was already owned and operated by New York City), the three former systems were no longer in competition with each other. Thus, elevated lines that duplicated underground lines were the first to close. Other elevated lines that did not create a redundancy in the system, such as the Bronx portion of the IRT Third Avenue Line and a major portion of the BMT Myrtle Avenue Line were later demolished. Two stations in which sections of track still operate have been demolished. The Dean Street station was demolished as part of the rebuilding of the BMT Franklin Avenue Line, and the Cortlandt Street station of the IRT Broadway–Seventh Avenue Line was demolished and subsequently rebuilt after it sustained heavy damage caused by the September 11 attacks. A number of stations were temporarily closed in Lower Manhattan in the aftermath of the attacks, see Closings and cancellations following the September 11 attacks.

The remaining closed stations and portions of stations are intact and are abandoned. The exception is the Court Street station: it is the site of the New York Transit Museum, a museum that documents the history of public transportation in New York City. The closed outer platforms of the Hoyt–Schermerhorn Streets station are occasionally used for filming purposes. The criterion for closing stations, as explained by NYC spokesman Charles Seaton, is not "because of low ridership. The only reason we have closed a station is because of its proximity to another station... The smaller stations are just as necessary as the larger ones."

Permanently closed but existing stations

These stations are still intact but are not currently served by passenger trains. This list does not include closed platforms on a different level of an open station.

Open stations with closed platforms or entrances

Closed platforms These stations are currently in operation, but contain abandoned platforms either adjacent to or on another level from the open platforms. The entries under the "Line" column refer to the line in question, even if the line is defunct. The entries under the "Opened" and "Closed" columns refer to the platform in question.
