Ahura Mazda
Ahura Mazda is the supreme god, but Zoroastrianism does not deny other deities. Ahura Mazda has yazatas ("good agents") some of which include Anahita, Sraosha, Mithra, Rashnu, and Tishtrya. Richard Foltz has put forth evidence that Iranians of Pre-Islamic era worshiped all these figures, especially Mithra and Anahita.
