The 4 Lexington Avenue Express^[3] is a rapid transit service in the A Division of the New York City Subway. Its route emblem, or "bullet", is colored forest green since it uses the IRT Lexington Avenue Line in Manhattan.^[4]

The 4 operates at all times. Daytime service operates between Woodlawn in the Bronx and Utica Avenue in Crown Heights, Brooklyn, making all stops on the IRT Jerome Avenue Line in the Bronx and express stops on the IRT Lexington Avenue Line in Manhattan and the IRT Eastern Parkway Line in Brooklyn; limited rush hour service, as well as late night service, is extended beyond Utica Avenue to and from New Lots Avenue in East New York, Brooklyn via the IRT New Lots Line. During rush hours in the peak direction, the 4 skips 138th Street–Grand Concourse.^[a] Late night service makes all stops along its entire route except for Hoyt Street. For up to an hour after evening events that are held at Yankee Stadium, a special downtown-only express service runs between 161st Street–Yankee Stadium and Bowling Green.

Until 1983, rush hour 4 trains originated and terminated at Flatbush Avenue–Brooklyn College in Brooklyn.
