Febris (lit. 'fever'), or Dea Febris (lit. 'goddess of fever'), is the Roman goddess of fevers, who embodied, but also protected people from fever and malaria. Because of this, Febris was a feared goddess whom people wanted the favour of. She does not have a myth of her own nor mentioned in a myth. Among her characteristic attributes are "shrewdness" and "honesty", according to Seneca the Younger's Apocolocyntosis.

Febris was accompanied by two daughters or sisters of her named Dea Tertiana and Dea Quartana, the goddesses of tertian and quartan fever of malaria because the fever would come back in every three or four days. Theodorus Priscianus mentions Saturn as Tertiana and Quartana's father.

The goddess Febris belongs to the apotropaic (turning away) deities (Lat. Dii averrunci) who have power over a specific evil: to impose it or to get rid of it. Romans worshipped Febris so she would not do harm to them. She may have originated from the Etruscan-Roman god of purification, Februus. Unlike some Roman deities, Febris was not derived from a Greek deity.
