Cay Sal Bank (Spanish: Placer de los Roques) is the third largest (after Great Bahama Bank and Little Bahama Bank) and the westernmost of the Bahama Banks. It is located between 23º27'N - 24º10'N and 079º25'W – 080º35'W. In a geographical sense, it is separate from the Bahamas proper as it is much closer to Cuba (from which it is separated by Nicholas Channel, at a distance of 50 km (31 mi)) than to the closest Bahamanian island. It is separated by Santaren Channel from the Great Bahama Bank, the western rim of which is 50 km (31 mi) to the east.
