*H₂éwsōs or *Haéusōs (lit. 'the dawn') is the reconstructed Proto-Indo-European name of the dawn goddess in the Proto-Indo-European mythology.
*H₂éwsōs is believed to have been one of the most important deities worshipped by Proto-Indo-European speakers due to the consistency of her characterization in subsequent traditions as well as the importance of the goddess Uṣas in the Rigveda.
Her attributes have not only been mixed with those of solar goddesses in some later traditions, most notably the Baltic sun-deity Saulė, but have subsequently expanded and influenced female deities in other mythologies.
