Who was the king of the Greek goddesses?

The king of the Greek goddesses is often considered to be Zeus, who is the king of the gods in Greek mythology. While Zeus is not a goddess himself, he rules over the pantheon that includes many powerful goddesses such as Hera, Athena, and Artemis. Hera, as Zeus's wife, is sometimes referred to as the queen of the goddesses. However, if you are specifically looking for a goddess, Hera is typically regarded as the foremost among them.
