Silver Bank (Spanish: Banco de la Plata)[1] is a submerged bank in the Atlantic Ocean north of the Dominican Republic and southeast of the territory of Turks and Caicos Islands.

Lying amongst the coral heads is the wrecked freighter Polyxeni, most of which rests above the surface.

The area is considered part of the Dominican Republic, as is Navidad Bank east of it.

On July 5, 1996, a Dominican presidential decree enlarged the area, declaring it the 'Sanctuary for Marine Mammals' (Santuario de Mamíferos Marinos).

The Silver Bank has long been a breeding and calving area for humpback whales.
