One Piece Novels

Twenty-two light novels based on One Piece have been published in Japan by Shueisha. Six of these novels are original, meaning their story is not based on existing media. The other sixteen are adaptations of the anime and movies.

Twelve of the novels have been re-released as a "Mirai Bunko Edition" (みらい文庫版). Mirai Bunko is Shueisha's imprint which publishes books for younger children, with simpler language.
