A gauntlet in heraldry is the armored glove of a knight, typically shown as a plate-metal hand with a cuff protecting the wrist. Its symbolism is firmly grounded in chivalry, courage, defense, and honorable service. Because the hand is the instrument of action, command, oath-taking, and combat, encasing it in armor suggests disciplined strength guided by duty rather than uncontrolled force. In a coat of arms, the gauntlet may signal military service, knightly ancestry, loyalty to a sovereign, or the obligation to protect law, faith, family, and community. It also recalls the well-known act of "throwing down the gauntlet," lending the charge a further sense of formal challenge, personal resolve, and readiness to answer a call to arms. A concise heraldic definition with artwork is available at Mistholme: Gauntlet.

The charge is expressive because its posture and contents shape its meaning. A gauntlet may be blazoned as dexter or sinister, open or clenched, upright or horizontal, empty or grasping a sword, spear, arrow, mace, or baton. An open gauntlet can suggest pledge, oath, command, or peaceful authority, while a clenched gauntlet emphasizes determination, resistance, and readiness for action. When it holds a weapon, the symbolism becomes more actively martial, pointing toward command and prepared force. The gauntlet also appears frequently in crests as part of a gauntleted arm, rising above the helm to create a vivid emblem of personal agency and noble responsibility.

Gauntlets and gauntleted arms are found throughout British and continental armory, particularly among families, military institutions, civic authorities, and professional bodies wishing to express guardianship, vigilance, and lawful strength. They are often shown grasping weapons to reinforce mottos of courage, constancy, or duty, and in some cases armored hand imagery may serve as canting heraldry, visually echoing a surname or office. For historical terminology and related entries on armored hands and arms, Parker's glossary remains an authoritative reference at A Glossary of Terms Used in Heraldry. Broader context on heraldic practice and the use of martial charges can be explored through the Heraldry Society. As a heraldic symbol, the gauntlet endures as a compact emblem of protected strength, moral resolve, and knightly identity.
