Minamoto no Yorimitsu (源 頼光, 948 – August 29, 1021), also known as Minamoto no Raikō, was a Japanese samurai and folk hero of the Heian period, who served the regents of the Fujiwara clan along with his brother Yorinobu, taking the violent measures the Fujiwara were themselves unable to take.

He is one of the earliest Minamoto of historical note for his military exploits, and is known for quelling the bandits of Ōeyama.

Yorimitsu served as commander of a regiment of the Imperial Guard, and as a secretary in the Ministry of War.

The tachi (long sword) 'Dōjigiri' owned by Tokyo National Museum and selected as a National Treasure and Tenka-Goken ("Five Swords under Heaven"), and 'Onikirimaru' owned by Tada Shrine, have a legend that Yorimitsu beheaded Shuten Dōji.
