The BMT Nassau Street Line is a rapid transit line of the B Division of the New York City Subway system in Manhattan. At its northern end, the line is a westward continuation of the BMT Jamaica Line in Brooklyn after the Jamaica Line crosses the Williamsburg Bridge into Manhattan. The Nassau Street Line continues south to a junction with the BMT Broadway Line just before the Montague Street Tunnel, after which the line reenters Brooklyn. Although the tracks merge into the Broadway Line south of Broad Street, there has been no regular service south of the Broad Street station since June 25, 2010. While the line is officially recognized as the Nassau Street Line,^[2] it only serves one station on Nassau Street: Fulton Street.

The line is served at all times by the J train. The Z provides supplemental rush hour service, operating in the peak direction. The M service has historically served the Nassau Street Line, but since 2010, the M has been rerouted via the Chrystie Street Connection to run on the IND Sixth Avenue Line, as a replacement for the V, which was discontinued due to financial shortfalls. The M continues to serve one Nassau Street Line station: the Essex Street station.
