<P> The Treasure Coast is a region of the eastern shore of the U.S. state of Florida . It is located on the Atlantic Coast and comprises Indian River, St. Lucie, Martin, and, in some definitions, Palm Beach counties . The region, whose name refers to the Spanish Treasure Fleet lost in a 1715 hurricane, evidently emerged from residents' desire to distinguish themselves from Miami and the Gold Coast region to the south . </P> <P> The area includes two metropolitan statistical areas designated by the Office of Management and Budget and used for statistical purposes by the Census Bureau and other agencies: the Port St. Lucie, Florida Metropolitan Statistical Area (comprising St. Lucie and Martin counties) and the Sebastian--Vero Beach, Florida Metropolitan Statistical Area (comprising Indian River County). Palm Beach county is part of the Miami - Fort Lauderdale - West Palm Beach, FL Metropolitan Statistical Area . </P>
