Udaydeva (Nepali: उदय देव) was the son of Shivadeva I and a Lichchhavi king of Nepal.
[1][2] Udaydeva was a son of King Shivadeva I and thus a legitimate heir apparent of Nepal.
[1] A coup plotted by Jishnu Gupta, of Abhira-Gupta dynasty, along with his brother Dhruvadeva in 624 forced him to flee to Tibet along with his family.
In Nepal, Jishnu Gupta was the highest authority and Dhruvadeva was a mere figurehead king.
His son Narendradeva later brought Nepal under his control ousting the Guptas and the lineage of Dhruvadeva.
