Union Street is a local station on the BMT Fourth Avenue Line of the New York City Subway. It is located at the corner of Fourth Avenue and Union Street in Brooklyn, New York City, serving the communities of Park Slope, Gowanus and Carroll Gardens. It is served by the R train at all times. The D and N trains also stop here during late nights, and a few rush-hour W trains stop here in the peak direction.

This underground station, which opened on June 22, 1915, has four tracks and two side platforms. The center express tracks are used by the D and N during daytime hours. A black and white curtain wall separates them from the local tracks.

Both platforms are columnless except for a section at their extreme north ends, where they were extended in the 1950s to accommodate the standard length of a B Division train (600 feet). Here, the columns are cream colored I-beams.

Each platform has one same-level fare control area in the center and there are no crossovers or crossunders to allow free transfer between directions. The Manhattan-bound side has a fare control area, a turnstile bank, token booth, and two street stairs. The one on the Manhattan-bound platform goes up to the southeast corner of Union Street and Fourth Avenue while the one on the Bay Ridge-bound platform goes up to the southwest corner. The Bay Ridge-bound side has a fare control area, a turnstile bank (but without a token booth), and two street stairs.
