The BMT Nassau Street Line is a rapid transit line of the B Division of the New York City Subway system in Manhattan. It is a continuation of the BMT Jamaica Line in Brooklyn after crossing the Williamsburg Bridge; it continues to a junction with the BMT Broadway Line just before the Montague Street Tunnel after which the line reenters Brooklyn (no revenue service south of Broad Street since June 25, 2010).

The line is served at all times by the J train. The Z provides supplemental rush hour service, operating in the peak direction.

While the line is officially recognized as the Nassau Street Line, it only serves one station on Nassau Street: Fulton Street.

The M service has historically served the Nassau Street Line. Since June 28, 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 on June 25, 2010 due to financial shortfalls. However, the M does continue to serve one Nassau Street Line station: the Essex Street station.
