Tuxedo Mask (タキシード仮面, Takishīdo Kamen), also known as Mamoru Chiba (地場 衛, Chiba Mamoru, renamed Darien Shields in some English adaptations), is a fictional character and one of the primary protagonists of the Sailor Moon media franchise created by Naoko Takeuchi. He disguises himself in order to support the series' central heroines, the Sailor Guardians. Wearing a mask to conceal his identity, he interferes with enemy operations, offers the Sailor Guardians advice, and sometimes physically aids them in battle.

Like the Sailor Guardians, Tuxedo Mask possesses a power item: a Sailor Crystal, which gives him guardianship over the planet Earth. He also has psychic powers, including psychometry and healing, which evolve and become important to the storyline in the manga, but which play only a minor role and remain static in the anime. Along with his primary love interest Sailor Moon, a significant player in much of the story, he has royal credentials in the "past life" storyline as well as in the future.
