The '''Court Square–23rd Street station''' is a [[New York City Subway]] [[metro station|station]] complex on the [[IND Crosstown Line]], the [[IRT Flushing Line]] and the [[IND Queens Boulevard Line]]. The complex is located in the vicinity of [[One Court Square]] in [[Hunters Point, Queens|Hunters Point]] and [[Long Island City, Queens]], and is served by the [[7 (New York City Subway service)|7]], [[E (New York City Subway service)|E]], and [[G (New York City Subway service)|G]] trains at all times (the latter of which terminates here), the [[M (New York City Subway service)|M]] train on weekdays, and the [[7d (New York City Subway service)|&lt;7&gt;]] express train during weekdays in the peak direction.

The complex comprises three originally separate stations, formerly known as the '''23rd Street–Ely Avenue station''' (Queens Boulevard Line), '''Long Island City–Court Square station''' (Crosstown Line), and '''45th Road–Court House Square station''' (Flushing Line). The Flushing Line station was the first to open, in 1916. The Crosstown Line station opened in 1933, followed by the Queens Boulevard Line station in 1939.

Two passageways were built to connect the three stations. The first was built in 1990, following the opening of the [[Citigroup]] office tower at One Court Square. In December 2001, this passageway came into greater use when G trains started to terminate at Court Square. A second passageway was completed between the Crosstown and Flushing Line stations in 2011. The Flushing and Crosstown Line stations were renamed "Court Square"; these stations became [[Americans with Disabilities Act of 1990|ADA-accessible]] in 2011 and 2023, respectively. The Queens Boulevard Line station, which is not fully ADA-compliant, was renamed "Court Square–23rd Street".

In 1913, the New York City Public Service Commission formalized the [[Dual Contracts]], specifying new lines or expansions to be built by the [[Interborough Rapid Transit Company]] (IRT) and the [[Brooklyn Rapid Transit Company]]. As part of the Dual Contracts, the IRT was to complete and open the [[Steinway Tunnel]] as part of the new [[IRT Flushing Line|Flushing subway line]].<ref name="Rogoff">{{cite journal|last=Rogoff|first=David|year=1960|title=The Steinway Tunnels|url=http://nycsubway.org/wiki/The_Steinway_Tunnels_%281960%29|journal=Electric Railroads|publisher=Electric Railroaders' Association|issue=29|access-date=February 28, 2021|archive-date=December 10, 2019|archive-url=https://web.archive.org/web/20191210061431/https://www.nycsubway.org/wiki/The_Steinway_Tunnels_(1960)|url-status=live}}</ref><ref name="Hood">{{cite book|last=Hood|first=Clifton|url=https://books.google.com/books?id=Az6dEkuGhccC|title=722 Miles: The Building of the Subways and How They Transformed New York|publisher=Johns Hopkins University Press|year=2004|isbn=978-0-8018-8054-4|edition=Centennial|location=Baltimore|pages=163–168|access-date=August 26, 2009|archive-date=April 25, 2022|archive-url=https://web.archive.org/web/20220425235930/https://books.google.com/books?id=Az6dEkuGhccC|url-status=live}}</ref>{{rp|168}} The tunnel, running under the [[East River]] with trolley loops on both the Manhattan and Queens sides, had sat unused since 1907, when test runs had been performed in the then-nearly-complete tunnel.<ref>{{Cite news|last=Burks|first=Edward C.|date=September 2, 1973|title=The Ill-Starred History Of an Old Subway Tunnel|language=en-US|work=The New York Times|url=https://www.nytimes.com/1973/09/02/archives/the-illstarred-history-of-an-old-subway-tunnel-by-edward-c-burks.html|access-date=April 8, 2020|issn=0362-4331|archive-date=May 4, 2022|archive-url=https://web.archive.org/web/20220504023723/https://www.nytimes.com/1973/09/02/archives/the-illstarred-history-of-an-old-subway-tunnel-by-edward-c-burks.html|url-status=live}}</ref> The route was to go from Times Square through the tunnel over to [[Long Island City]] and from there continue toward [[Flushing – Main Street (IRT Flushing Line)|Flushing]].<ref name="Rogoff" /><ref>{{cite book|url=https://www.nycsubway.org/wiki/Chapter_1:_Dual_System_of_Rapid_Transit|title=New Subways For New York: The Dual System of Rapid Transit Chapter 1: Dual System of Rapid Transit|publisher=New York State Public Service Commission|year=1913|access-date=February 28, 2021|archive-date=January 11, 2021|archive-url=https://web.archive.org/web/20210111162732/https://www.nycsubway.org/wiki/Chapter_1:_Dual_System_of_Rapid_Transit|url-status=live}}</ref>

=== IND stations ===
In the late 1920s and early 1930s, the city-owned [[Independent Subway System]] (IND) constructed the first sections of the [[IND Crosstown Line|Crosstown]] and [[IND Queens Boulevard Line|Queens Boulevard]] Lines. The Crosstown Line station at Court Square was the first Queens station on either line to be built; its structure was completed in July 1930, and the tilework and equipment were installed afterward.<ref name="LIDaily-INDCtSq-July1930">{{cite news|date=July 19, 1930|title=Court Square Station Of New Tube Completed; War Over Van Alst Ave|page=1|work=Long Island Daily Star|agency=[[Fultonhistory.com]]|url=http://fultonhistory.com/highlighter/viewer/?file=http%3A%2F%2Ffultonhistory.com%2FNewspaper%252015%2FBrooklyn%2520NY%2520Daily%2520Star%2FBrooklyn%2520NY%2520Daily%2520Star%25201930%2FBrooklyn%2520NY%2520Daily%2520Star%25201930%2520-%25202102.pdf&highlightsFile=http%3A%2F%2Ffultonhistory.com%2Fhighlighter%2Fhits%2Fbf5dfe364c64162631341118e54b9106#page=1|access-date=July 27, 2016|via=Fulton History}}</ref><ref name="LIDaily-INDCtSq-July1930-pg3">{{cite news|date=July 19, 1930|title=Court Square Station Of New Tube Completed; War Over Van Alst Ave.|page=3|work=Long Island Daily Star|agency=[[Fultonhistory.com]]|url=http://fultonhistory.com/Newspaper%2015/Brooklyn%20NY%20Daily%20Star/Brooklyn%20NY%20Daily%20Star%201930/Brooklyn%20NY%20Daily%20Star%201930%20-%202104.pdf|access-date=July 27, 2016}}</ref> On August 19, 1933, the IND opened the Court Square station as part of the first leg of the IND Crosstown Line.

This station has an elevated station house beneath the tracks at the extreme south end.

Although G service terminates here, the tracks themselves continue north and merge with the [[60th Street Tunnel Connection]] to form the [[IND Queens Boulevard Line]]'s local tracks just south of [[Queens Plaza (IND Queens Boulevard Line)|Queens Plaza]]. This section of the tracks are not used in regular service, though until April 19, 2010, trains traveled over this connection to continue to [[Forest Hills–71st Avenue (IND Queens Boulevard Line)|Forest Hills–71st Avenue]] at various times of the day.

Three staircases from the platform go up to the full length [[mezzanine (architecture)|mezzanine]] above and a passageway within [[fare control]] connects the station to the Queens Boulevard platform. All fare control areas are unstaffed, containing just [[HEET turnstile|full height turnstiles]].

After the [[IND 63rd Street Line]] was connected to the Queens Boulevard Line in December 2001, during a project known as the "63rd Street Connector",<ref name="nyt 200105" /> another unstaffed entrance was added to the south end of the [[mezzanine (architecture)|mezzanine]] at 45th Road.
