The L 14th Street–Canarsie Local is a rapid transit service in the B Division of the New York City Subway, providing full-time service along the entire length of the two-tracked BMT Canarsie Line and its route emblem, or "bullet", is colored light slate gray. The L operates between Eighth Avenue in Chelsea, Manhattan, and Rockaway Parkway in Canarsie, Brooklyn. It also briefly enters Queens at Halsey Street, serving the neighborhood of Ridgewood. It is the first New York City Subway service to be automated using communications-based train control.

The L, being a local train, was originally given the LL designation when letters were assigned to the BMT division. From 1928 to 1967, the same service was assigned the BMT number 16.

In 1924, part of the eventual 14th Street–Canarsie Line opened, called the "14th Street–Eastern District Line" (commonly the "14th Street–Eastern Line"), and was given the number 16. This was extended east, and in 1928 it was joined to the existing BMT Canarsie Line east of Broadway Junction. Since that time, the 14th Street–Canarsie Line service has operated as it is today, except for an extension from Sixth Avenue to Eighth Avenue, which opened on May 30, 1931 to connect to the new Eighth Avenue Subway. The Eighth Avenue Terminal was originally built in IND style and has been restored to BMT style like Fulton Street and Broad Street. During rush hours, express service ran nonstop between Lorimer Street and Myrtle–Wyckoff Avenues. (Locals usually ran from Eighth Avenue to Myrtle–Wyckoff Avenues or Atlantic Avenue at these times.)
