Bensonhurst actually has a clearly defined border, with Gravesend to the southeast, Midwood to the east, Borough Park to the north, Dyker Heights to the west, and Bath Beach to the southwest. Starting at the neighborhood's southern tip at the corner of Stillwell Avenue and 86th Street, the border runs north along Stillwell Avenue to Kings Highway, east to McDonald Avenue, north to 60th Street, northwest to 13th Avenue, south to 86th Street, and southeast back to Stillwell Avenue.

Bensonhurst is served by two branches of the New York City Subway system: the D/M elevated subway line, also called the BMT West End Line, at 62nd Street, 71st Street, 79th Street, 18th Avenue, 20th Avenue,  Bay Parkway and 25th Avenue Stations
