Ingjald illråde or Ingjaldr hinn illráði (Ingold Illruler or Illready) was a semi-legendary Swedish king of the House of Ynglings, son and successor of King Anund, and the father and predecessor of King Olof Trätälja. As with many of the 5th-7th century Yngling Kings of Sweden, his historicity is contested.
Ingjald is mentioned in medieval historiographical sources including the Ynglinga saga, Historia Norvegiæ, Hervarar saga, Upplendinga Konungum, Þorsteins saga Víkingssonar and Íslendingabók. The setting of Þorsteins saga Víkingssonar is roughly the 7th century. Johannes Magnus in his 16th-century list of kings places Ingjald (Ingevallus, Ingellus) in AD 883.
