Valdar was the name of several legendary Danish kings.
The Hervarar saga tells the tale of a Valdar who was viceroy of Denmark under Ivar Vidfamne c. 695 AD. This Valdar was the father of Randver who reigned in the early 700s, and the father of Harald Wartooth who was king of Denmark and Sweden from about 715 to about 770.

The Skjöldunga saga and Hversu Noregr byggdist tell the tale of a Valdar who succeeded Hrólfr Kraki as King of Scania in the 6th century. This Valdar was the father of Harald the Old who was born c. 568.

Harald the Old
The Hervarar saga tells that Ivar Vidfamne made Valdar the viceroy of Denmark and gave him his daughter Alfhild. When Valdar died, his son Randver became the king of Denmark, while his son Harald Wartooth became the king of Götaland or Gotland. In the Hervarar saga, the name Valdar also appears in a poem together with other kings and nations:
Valdar is named as a king of the Danes in Guðrúnarkviða II (stanza 19):
Hversu Noregr byggdist
According to Hversu Noregr byggdist, a Valdar was the son of Roar (Hroðgar) of the house of Skjöldung (Scylding). This source makes Valdar the father of Harald the Old, the father of Halfdan the Valiant, the father of Ivar Vidfamne. If he is of the same origin as the Valdar of Hervarar saga, this account adds four generations (Harald the Old, Halfdan the Valiant, Ivar Vidfamne and effectively Ivar's daughter Alfhild/Auðr who was Harald Wartooth's mother according to all accounts) between Valdar and Harald Wartooth, who was Valdar's son according to the Hervarar saga.
The Skjöldunga saga tells that a Valdar disputed that Rörek, the cousin of Helgi (Halga) succeeded Hrólfr Kraki (Hroðulf) as the king of the Daner. After the war, Rörek took Zealand, while Valdar took Skåne. If based on the same tradition as Hversu Noregr byggdist, Valdar had the right to claim the throne being the son of the former king Hróarr (Hroðgar).
