Tottenville is a neighborhood on the South Shore of Staten Island, New York City. It is the southernmost neighborhood and settlement in both New York City and New York State, as well as the westernmost neighborhood in New York City. Tottenville is bounded on three sides by water: the south side abuts the New York Bight while the west and north sides are bordered by the Arthur Kill. Nassau Place, Bethel Avenue and Page Avenue form the neighborhood's eastern border.

The South Shore is a geographical term applied to the area in the New York City borough of Staten Island, south and east of the island's ridge of hills along the waterfront and adjacent areas from the Narrows to the mouth of the Arthur Kill. Many observers prefer to restrict its scope to the neighborhoods located between the shoreline of Raritan Bay on one side and Richmond Creek and Fresh Kills on the other, thus encompassing the neighborhoods of Great Kills to Tottenville only. Those who use this narrower definition of the "South Shore" prefer the term "East Shore" for the communities that lie along Lower New York Bay, and inland for approximately 2 to 2+1⁄2 miles, from Bay Terrace and Richmondtown to as far north as Grasmere and Concord. The South Shore is represented in the New York City Council by Joe Borelli.
