Vesta (Classical Latin: [ˈwɛsta]) is the virgin goddess of the hearth, home, and family in Roman religion. She was rarely depicted in human form, and was often represented by the fire of her temple in the Forum Romanum. Entry to her temple was permitted only to her priestesses, the Vestals, who tended the sacred fire at the hearth in her temple. As she was considered a guardian of the Roman people, her festival, the Vestalia (7–15 June), was regarded as one of the most important Roman holidays. During the Vestalia matrons walked barefoot through the city to the sanctuary of the goddess, where they presented offerings of food. Such was Vesta's importance to Roman religion that hers was one of the last republican pagan cults still active following the rise of Christianity until it was forcibly disbanded by the Christian emperor Theodosius I in AD 391.

The myths depicting Vesta and her priestesses were few, and were limited to tales of miraculous impregnation by a phallus appearing in the flames of the hearth—the manifestation of the goddess. Vesta was among the Dii Consentes, twelve of the most honored gods in the Roman pantheon. She was the daughter of Saturn and Ops, and sister of Jupiter, Neptune, Pluto, Juno, and Ceres. Her Greek equivalent is Hestia.

In the Ancient Greek religion, Hestia (/ˈhɛstiə, ˈhɛstʃə/; Greek: Ἑστία, "hearth" or "fireside") is the virgin goddess of the hearth, the right ordering of domesticity, the family, the home, and the state. In Greek mythology, she is the firstborn child of the Titans Cronus and Rhea

Customarily, in Greek culture, Hestia received the first offering at every sacrifice in the household. In the public domain, the hearth of the prytaneum functioned as her official sanctuary, and, when a new colony was established, a flame from Hestia's public hearth in the mother city would be carried to the new settlement. The goddess Vesta is her Roman equivalent.
