The 3 Seventh 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 red since it uses the IRT Broadway–Seventh Avenue Line through most of Manhattan.^[4]

The 3 operates 24 hours a day, although service patterns vary based on the time of day. Daytime service operates between 148th Street in Harlem, Manhattan and New Lots Avenue in East New York, Brooklyn, making express stops in Manhattan (between 96th and Chambers Streets) and all stops in Brooklyn. Overnight service short turns at 34th Street–Penn Station in Midtown Manhattan and does not operate to or from New Lots Avenue.

The 3 train formerly ran to City Hall or South Ferry in Manhattan, and was later rerouted to Flatbush Avenue–Brooklyn College in Brooklyn. In 1983, it was rerouted to New Lots Avenue.
