Rai Uchiha (うちはライ, Uchiha Rai) was a shinobi of the Uchiha clan.

Born to the Uchiha clan, Rai was able to awaken the Sharingan in his youth, as well as his own Mangekyō Sharingan.

During the continuous struggle between shinobi clans, Rai and his clansmen faced an opposing force who quickly wiped out Rai's comrades with a trap. However, Rai nullified the outcome by sacrificing his left eye in order to use Izanagi. With the enemies slaughtered, he boldly declared that the Uchiha clan was invincible due to the powerful dōjutsu.

His prowess in using the forbidden technique made him the leader of the small group of his shinobi until he was challenged by Baru Uchiha, who was able to kill Rai by using Izanagi himself.
