The Gulf of Cádiz (Spanish: Golfo de Cádiz, Portuguese: Golfo de Cádis) is the arm of the Atlantic Ocean between Cabo de Santa Maria, the southernmost point of Mainland Portugal and Cape Trafalgar at the western end of the Strait of Gibraltar. Two major rivers, the Guadalquivir and the Guadiana, as well as smaller rivers, like the Odiel, the Tinto, and the Guadalete, reach the ocean here. The Gulf of Cádiz is located in the north-eastern Atlantic Ocean between 34°N and 37°15′N and 6°W to 9°45′W. It is enclosed by the southern Iberian and northern Moroccan margins, west of Gibraltar Strait.
