The Jamaica Line (also known as the Broadway Line or Broadway (Brooklyn) Line) is an elevated rapid transit line of the B Division of the New York City Subway, in Brooklyn and Queens, New York City, United States. It runs from the Williamsburg Bridge southeast over Broadway to East New York, Brooklyn, and then east over Fulton Street and Jamaica Avenue to Jamaica, Queens. In western Jamaica, the line goes into a tunnel, becoming the lower level of the Archer Avenue Line in central Jamaica. The J and Z trains serve the entire length of the Jamaica Line, and the M serves the line west of Myrtle Avenue.

The longest elevated line in the system, the Jamaica Line includes the oldest existing elevated structure in the subway system - the original 1885 line of the Brooklyn Elevated Railroad, the BMT Lexington Avenue Line - between Gates Avenue and Van Siclen Avenue, as well as the newest elevated structure - the 1988 ramp into the underground Archer Avenue Line.
