Juno was an ancient Roman goddess, the protector and special counsellor of the state. She was equated to Hera, queen of the gods in Greek mythology and a goddess of love and marriage. A daughter of Saturn and Ops, she was the sister and wife of Jupiter and the mother of Mars, Vulcan, Bellona, Lucina and Juventas. Like Hera, her sacred animal was the peacock. Her Etruscan counterpart was Uni, and she was said to also watch over the women of Rome. As the patron goddess of Rome and the Roman Empire, Juno was called Regina ("Queen") and was a member of the Capitoline Triad, centered on the Capitoline Hill in Rome, and also including Jupiter, and Minerva, goddess of wisdom.

Religion in ancient Rome consisted of varying imperial and provincial religious practices, which were followed both by the people of Rome as well as those who were brought under its rule.
