The F and <F> Queens Boulevard Express/Sixth Avenue Local are two rapid transit services in the B Division of the New York City Subway. Their route bullets are colored orange, since they use and are part of the IND Sixth Avenue Line in Manhattan.
The F operates at all times between 179th Street in Jamaica, Queens and Stillwell Avenue in Coney Island, Brooklyn. During rush hours, most alternate trains originate and terminate at Kings Highway in Gravesend, Brooklyn instead of Stillwell Avenue. During the daytime, the F runs express in Queens between Forest Hills–71st Avenue and 21st Street–Queensbridge; during the nighttime, it makes all stops in-between both stations.

This express service was introduced in September 2019. In Brooklyn, local service is denoted as (F) in a circle-shaped bullet while express service is denoted as <F> in a diamond-shaped bullet.
From 1968 to 1976, the F ran express along the IND Culver Line in Brooklyn. The F also ran via the 53rd Street Tunnel until moving to the 63rd Street Tunnel in 2001, except between August 2023 and March 2024 when service between Queens and Manhattan was rerouted to the 53rd Street Tunnel due to track replacement. Since the 1990s, there have been calls to restore partial express service in Brooklyn from Jay Street–MetroTech to Church Avenue, although this has been controversial. The limited express <F> service between Jay Street and Church Avenue started on September 16, 2019, with two trains in the peak direction during rush hours. The F has a weekday ridership of 600,000.
