Dažbog (Proto-Slavic: ,Serbo-Croatian: Dabog, Daždbog, Dajbog; Belarusian: Дажбог, Bulgarian: Даждбог, Polish: Dadźbóg, Russian: Даж(д)ьбог, Ukrainian: Дажбог), alternatively Daždźboh (Belarusian: Даждзьбог), Dazhbog, Dajbog, Dazhdbog, or Dadzbóg, was one of the major gods of Slavic mythology, most likely a solar deity and possibly a cultural hero. He is one of several authentic Slavic gods, mentioned by a number of medieval manuscripts, and one of the few Slavic gods for which evidence of worship can be found in all Slavic nations.
Dažbog (or Dažboh) is mentioned in the Primary Chronicle, a history of early Kievan Rus' as one of seven gods whose statues Prince Vladimir the Great erected in front of his palace in Kiev in 980, when he came to the throne. The name is also mentioned in the Hypatian Codex, as well as in the medieval Russian epic The Tale of Igor's Campaign.
The Proto-Slavic reconstruction is , and is composed of *dadjь, imperative of the verb "to give", and the noun "god". The original meaning of Dažbog would thus, according to Dubenskij, Ognovskij and Niderle, be "giving god", "god-giver, "god-donor".
