In ancient Roman mythology, Salacia was the female divinity of the sea, worshipped as the goddess of salt water who presided over the depths of the ocean. She was the wife and queen of Neptune, god of the sea and water. That Salacia was the wife of Neptune is implied by Varro, and is positively affirmed by Seneca, Augustine and Servius. She is identified with the Greek goddess, Amphitrite, wife of Poseidon.
