Atargatis or Ataratheh (; ) was the chief goddess of northern Syria in Classical Antiquity. Ctesias also used the name Derceto for her, and the Romans called her Dea Syriae ("Syrian goddess"). Primarily she was a goddess of fertility, but, as the baalat ("mistress") of her city and people, she was also responsible for their protection and well-being. Her chief sanctuary was at Hierapolis, modern Manbij, northeast of Aleppo, Syria. She is sometimes described as a mermaid-goddess, due to identification of her with a fish-bodied goddess at Ascalon. However, there is no evidence that Atargatis was worshipped at Ascalon, and all iconographic evidence shows her as anthropomorphic.
