The 2 Seventh Avenue Express 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.

The 2 operates 24 hours daily between 241st Street in Wakefield, Bronx, and Flatbush Avenue–Brooklyn College in Flatbush, Brooklyn; limited rush hour service in the reverse-peak direction originates and terminates at New Lots Avenue in East New York, Brooklyn instead of Flatbush Avenue. Daytime service makes express stops in Manhattan (between 96th and Chambers Streets) and all stops in the Bronx and Brooklyn; overnight service makes all stops along the full route.

Historically, 2 trains have also run to Crown Heights–Utica Avenue or New Lots Avenue. They ran exclusively on the IRT New Lots Line until 1983, when the 2 was routed to Flatbush Avenue. This is still the case with some rush-hour trains, albeit just to New Lots Avenue.
