The G Crosstown Local is an 11.4-mile-long (18.3 km)rapid transit service in the B Division of the New York City Subway. Its route emblem, or "bullet", is colored lime green since it uses the IND Crosstown Line. The G operates at all times between Court Square in Long Island City, Queens and Church Avenue in Kensington, Brooklyn via the IND Crosstown and Culver lines. In Queens, it only serves two stations – Court Square and 21st Street, both in Long Island City – but previously served all stations to and from 71st Avenue in Forest Hills on the IND Queens Boulevard Line.

It is the only non-shuttle service in the system that does not serve Manhattan and suffers from frequent disruptions and poor service, leading to criticism from politicians and residents of the neighborhoods through which it travels.

The original Brooklyn–Queens Crosstown Local service began on August 19, 1933, as a shuttle between Queens Plaza on the IND Queens Boulevard Line and Nassau Avenue. This service was designated GG because the IND used double letters to indicate local service. Starting on April 24, 1937, GG trains were extended to Forest Hills–71st Avenue during rush hours, serving as the Queens Boulevard local while E trains ran express west of Continental Avenue. The entire IND Crosstown Line was completed on July 1, 1937, including the connection to the IND Culver Line.GG service ran at all times between Forest Hills–71st Avenue and Church Avenue. Soon after, it was cut back to Smith–Ninth Streets.
