Emperor Itoku (懿徳天皇, Itoku-tennō^?); also known as Ooyamatohikosukitomo no Mikoto; was the fourth emperor of Japan according to the traditional order of succession.

No firm dates can be assigned to this emperor's life, but he is conventionally considered to have reigned from 510 BC to 476 BC.

Modern scholars have come to question the existence of at least the first nine emperors; Itoku's descendant, Emperor Sujin is the first that many agree might have actually existed. The name Itoku-tennō was assigned to him posthumously by later generations.

Itoku is regarded by historians as a "legendary emperor" and there is a paucity of information about him. There is insufficient material available for further verification and study. The reign of Emperor Kinmei (c. 509 – 571 AD), the 29th emperor, is the first for which contemporary historiography is able to assign verifiable dates; However, the conventionally accepted names and dates of the early emperors were not to be confirmed as "traditional" until the reign of Emperor Kanmu (737–806), the 50th sovereign of the Yamato dynasty.

In the Kojiki and Nihon Shoki only his name and genealogy were recorded. He is believed to be the son of Emperor Annei; and his mother is believed to have been Nunasoko-Nakatsu-hime, who was the granddaughter of Kotoshiro-Nushi-no-kami. The Japanese have traditionally accepted this sovereign's historical existence, and an Imperial misasagi or tomb for Itoku is currently maintained; however, no extant contemporary records have been discovered that confirm a view that this historical figure actually reigned. He is considered to have been the third of eight emperors without specific legends associated with them, also known as the "eight undocumented monarchs" (欠史八代, Kesshi-hachidai^?).
