Richmond Valley is bordered on the north by Pleasant Plains, to the south by Tottenville, to the west by the Arthur Kill, and to the east by the Lower New York Bay.
Once considered part of Tottenville, Richmond Valley gained a separate identity when the Richmond Valley (Staten Island Railway station) was opened soon after the railroad was extended to Tottenville in 1860.
Today the neighborhood is noted chiefly for being the site of the terminus, on the Staten Island side, of the Outerbridge Crossing, which connects the island to Perth Amboy, New Jersey, across the Arthur Kill.
Richmond Valley is served by the station of the same name on the Staten Island Railway.
Express bus service to and from Manhattan is provided by the SIM26 along Amboy Road.
