Orochimaru (大蛇丸) is a fictional character from Naruto, a manga series created by Masashi Kishimoto. Orochimaru is a former ninja from the village of Konohagakure who is well known for work in wars which earned him the title of Sannin and becomes a terrorist as a means to cheat death, and built his own ninja village Otogakure. He succeeds to some extent in obtaining immortality by transferring between different host bodies, which became one of his driving motivations throughout the series as he targets Sasuke Uchiha for his genetic heritage. By the events of Boruto: Naruto Next Generations, he has seemingly redeemed himself and has sent his experiment Mitsuki to Konoha to become a ninja. Orochimaru has appeared in media outside the Naruto anime and manga, including several video games.

Naruto is a Japanese manga series written and illustrated by Masashi Kishimoto.

The story is told in two parts: the first is set in Naruto's pre-teen years, and the second in his teens. The series is based on two one-shot manga by Kishimoto: Karakuri (1995), which earned Kishimoto an honorable mention in Shueisha's monthly Hop Step Award the following year, and Naruto (1997).
