The IRT Flushing Line is a rapid transit route of the New York City Subway system, named for its eastern terminal in Flushing, Queens. It is operated as part of the A Division. The Interborough Rapid Transit Company (IRT), a private operator, had constructed the section of the line from Flushing, Queens, to Times Square, Manhattan between 1915 and 1928. A western extension was opened to Hudson Yards in western Manhattan in 2015, and the line now stretches from Flushing to Chelsea, Manhattan. It carries trains of the 7 local service, as well as the express <7> during rush hours in the peak direction.^[2] It is the only currently operational IRT line to serve Queens.

It is shown in the color purple on station signs, the official subway map, and internal route maps in R188 cars. Before the line was opened all the way to Flushing in 1928, it was known as the Corona Line or Woodside and Corona Line. Prior to the discontinuation of BMT services in 1949, the portion of the IRT Flushing Line between Times Square and Queensboro Plaza was known as the Queensboro Line. Since the mid-2010s, the line's signal system has been converted to an automated system.

The Flushing Line has various styles of architecture, which range from steel girder elevated structures to European-style concrete viaducts. The underground stations have some unique designs as well. The designs include Hunters Point Avenue, which is in an Italianate style; Grand Central–42nd Street, which is a single round tube similar to a London Underground station; and 34th Street–Hudson Yards, which, with its deep vault and spacious interior, resembles a Washington Metro station.
