In Norse mythology, Dellingr (Old Norse possibly "the dayspring" or "shining one" is a god. Dellingr is attested in the Poetic Edda, compiled in the 13th century from earlier traditional sources, and in the Prose Edda, written in the 13th century by Snorri Sturluson. In both sources, Dellingr is described as the father of Dagr, the personified day. The Prose Edda adds that, depending on manuscript variation, he is either the third husband of Nótt, the personified night, or the husband of Jörð, the personified earth. Dellingr is also attested in the legendary saga Hervarar saga ok Heiðreks. Scholars have proposed that Dellingr is the personified dawn and his name may appear both in an English surname and place name.
