The J Nassau Street Local and Z Nassau Street Express^[3] are two rapid transit services in the B Division of the New York City Subway. Their route emblems, or "bullets", are colored brown since they use the BMT Nassau Street Line in Lower Manhattan.^[4]

The J operates 24 hours a day, while the Z, operating as the rush hour variant to the J,^[5] operates weekday rush hours in the peak direction only; both services operate between Jamaica Center–Parsons/Archer station in Jamaica, Queens, and Broad Street in Lower Manhattan. When the Z operates, the two services form a skip-stop pair between Sutphin Boulevard–JFK and Myrtle Avenue-Broadway. Weekday rush hour and midday J service makes express stops in Brooklyn between Myrtle and Marcy Avenues, while weekday evening, weekday daytime and daily overnight service makes all stops along the full route.

The J/Z's current skip-stop pattern was implemented in 1988. The J/Z is derived from four routes:

• The JJ/15 between Broad or Chambers Streets in Lower Manhattan and 168th Street in Queens
• The KK between 57th Street/Sixth Avenue in Midtown Manhattan and 168th Street in Queens
• The QJ between Brighton Beach in Brooklyn and 168th Street in Queens
• The 14 between Broad or Chambers Streets in Lower Manhattan and Canarsie–Rockaway Parkway in Brooklyn
