The Bay of Campeche, or Campeche Sound, is a bight in the southern area of the Gulf of Mexico, forming the north side of the Isthmus of Tehuantepec. It is surrounded on three sides by the Mexican states of Campeche, Tabasco and Veracruz. The area of the bay is 6,000 square miles (16,000 km2) and maximum depth of the bay is approximately 180 feet (55 m). It was named by Francisco Hernández de Córdoba and Antón de Alaminos during their expedition in 1517.
