The 6 (Lexington Avenue Local) is a train line in the New York Subway. It was the first line of the subway to be built, and was opened by the Interborough Rapid Transit, and was originally named the East Side Line. It runs from Pelham Bay Park station in the Bronx to Lower Manhattan. Being part of the Interborough Rapid Transportation East Side Line Division, it shares its route and stations with the 4 (Lexington Avenue Jerome Avenue Express) and the 5 (Lexington Avenue Express) from 125th Street station to Brooklyn Bridge-City Hall station, where the 6 line ends.

The 6 is the most crowded line because it is the only local train to service the East Side of Manhattan. Service is frequent during the day, and it runs 24 hours a day.

During rush hours, some 6 trains run express in the Bronx, skipping certain local stops.

The 6 also contains the most abandoned subway stations of any subway line in New York City, as it is the oldest line in New York. Abandoned stations include City Hall, Worth Street, and 18th Street. These stations were abandoned when platforms were lengthened to hold 10 subway cars instead of five, making certain stations redundant. A case in point is 18th Street station, as there would be an entrance to 14th Street-Union Square station on 16th street, and an entrance to 23rd Street station on 20th Street.

The 6 was the train in the 1974 film The Taking of Pelham One Two Three, about hijackers holding hostages inside a subway car. The 6 was also the train Jennifer Lopez rode in her early days to school. Her 1999 album is called "On the 6". This is a reference to the 6 train she rode.
