The R Broadway Local is a service of the New York City Subway. It is colored sunflower yellow on the route sign (either on the front and/or side – depending on equipment used) and on station signs and the NYC Subway map, as it represents a service provided on the BMT Broadway Line in Manhattan.

The R service operates at all times. During the day, trains run between 71st Avenue in Forest Hills, Queens and 95th Street in Bay Ridge, Brooklyn via the IND Queens Boulevard Line and BMT Fourth Avenue Line, making all stops. During late nights, it operates as a shuttle within Brooklyn between 36th and 95th Streets with northbound trains bypassing 53rd and 45th Streets.

The R is the longest New York City Subway service without an elevated section, although there is a small opening between 59th Street and Bay Ridge Avenue in Brooklyn when the Fourth Avenue Line passes over a valley containing the Long Island Rail Road's Bay Ridge Branch tracks.

The service has been called the Silicon Subway, for its social role: connecting the areas of Manhattan where many technical firms are located in the 2010s, with the areas in Brooklyn where their workers typically live.
