The Armorer is a fictional character in the Star Wars franchise who appears in the Disney+ television series The Mandalorian and The Book of Boba Fett. Dressed in red body armor and a gold helmet, she is the leader of a tribe of Mandalorian warriors, which includes the title character of The Mandalorian. A mysterious, patient, and intelligent character, the Armorer provides spiritual guidance for the clan, and forges and repairs their armor.

Jon Favreau, the creator and showrunner of The Mandalorian, was among the creators of the Armorer. The character was partially inspired by the films of Akira Kurosawa, as well as the history and culture of the samurai, particularly in the character's slow-paced movement and aura of authority. The Armorer is portrayed by Emily Swallow, who provides both the character's voice and live-action performance, while her stunts are performed by Lauren Mary Kim. When Swallow auditioned for the role, she knew little about the character and did not know it was for a Star Wars series.

The voice Swallow uses for the Armorer has elements of British and Mid-Atlantic accents, which stemmed from a suggestion made by a casting associate during her audition. She also partially modeled the Armorer's voice after characters from the Lord of the Rings film series. Aspects of The Mandalorian director Deborah Chow's personality influenced Swallow's performance. Kim's combat style in the Armorer's fight scenes was inspired by the Filipino martial art known as Kali.

The Armorer's costume took several weeks to make, and it proved to be challenging to perform in due to limited visibility and the fact that small movements in the costume were very noticeable. Swallow wore the helmet and armor costume for up to nine hours at a time during filming. The Armorer has been received positively by fans and reviewers alike and has been described as a fan favorite.

The Armorer appeared in three episodes in the first season of The Mandalorian. She is the leader of a tribe of Mandalorian warriors on the planet Nevarro, where they live in a secret enclave. She provides spiritual guidance for the clan, and forges and repairs their armor. Little is revealed about her backstory, and, like other Mandalorians, she wears highly durable armor and conceals her face with a helmet that she never publicly removes. The Mandalorians are in hiding after having suffered persecution by the Galactic Empire, and although the Empire has fallen out of power by the time of The Mandalorian, the clan has not yet regained its former status or power.

The Armorer made her first appearance in the series premiere "Chapter 1: The Mandalorian". The show's protagonist, a bounty hunter known simply as "The Mandalorian", brings her money he received from having collected his most recent bounties, including a bar of beskar steel, a very rare form of metal used to make Mandalorian armor. The Armorer explains that the Empire stole the beskar from the Mandalorians during an event known as "the Great Purge". She uses the beskar to make a single shoulder spaulder for the Mandalorian, and asks whether he has yet identified his "signet", a symbol used to identify clans of Mandalorians. When he says that he has not, she assures him that he will soon. The Armorer says the remaining beskar will be used to assist the "foundlings", a term for children who were not born Mandalorian but rather adopted into their culture. This pleases the Mandalorian because he was a foundling himself. As the Armorer works on his armor, the Mandalorian has flashbacks to his youth, when his family was killed.

The Armorer reappears in the episode "Chapter 3: The Sin", in which the Mandalorian brings her a large amount of beskar, which he received as a bounty for collecting a young alien known as "the Child" and turning him over to a remnant of the fallen Empire. The Armorer uses the steel to make a full cuirass for him. She also makes him a set of explosive projectiles called "whistling birds", named for the whistling noises they make as they fly toward their target. Another clan member named Paz Vizla reprimands the Mandalorian for working with the Empire to obtain the beskar, which leads to a brief fight between the two warriors. The Armorer quickly and quietly defuses the quarrel, reminding them the Empire no longer exists and that it is good the beskar has been returned to the tribe. She speaks about cowardice, honor, and the "Way of the Mandalore", which serves as the tribe's religion and creed. Later, off-screen, the Mandalorians on Nevarro are largely wiped out by the Imperial remnant after the tribe reveals itself at the conclusion of "Chapter 3: The Sin" to assist the Mandalorian. The Armorer is one of the few members of the clan to survive.

In the first-season finale "Chapter 8: Redemption", the Mandalorian and his allies come to the Mandalorian enclave while fleeing from attacking Imperials, only to find it unoccupied except for the Armorer, following the elimination of most of the tribe. The Armorer explains that some Mandalorian warriors may have survived and fled off-world. She is collecting the armor of the fallen Mandalorian warriors and melting it down for salvage. When the Mandalorian presents the Child and reveals he has supernatural powers, the Armorer tells him about the Jedi Order, of which most other characters in the show are not aware. She speaks of the history of the Jedi warriors and their past associations with the Way of the Mandalore, sharing a story from "eons past" about a battle between the Jedi and "Mandalore the Great", a mythological figure in Mandalorian culture. This marks the first time the Jedi are identified by name in The Mandalorian.
