In heraldry, the horseshoe is a practical yet auspicious symbol of good fortune, protection, travel, and honorable labor. Its everyday role in caring for the horse connects it with mobility, service, cavalry, transport, farming, and the skilled trades of the farrier and blacksmith. Because horses were essential to war, agriculture, trade, and communication, the horseshoe could suggest readiness for movement, reliable support, and the infrastructure behind noble or military life. Its long-standing reputation as a charm against misfortune also gave it a popular meaning of blessing, safety, and prosperity.

The horseshoe is particularly common in canting arms, where it visually echoes a family or place name, and in arms connected with farriery, smithing, coaching, inns, roads, and horse breeding. It may be shown with the ends upward, a familiar sign of luck in popular tradition, or simply arranged as a heraldic charge without that folklore being central. The Worshipful Company of Farriers in London naturally uses horseshoes and horse-related symbolism in its armorial tradition, reflecting the craft’s close bond with equine care and metalwork.

As a charge, the horseshoe is visually strong and easily repeated, so it often appears in groups, on bends, around crosses, or as part of a crest. It may be combined with hammers, anvils, nails, horses, or wheels to indicate occupation, local industry, or a transport heritage. Broader examples are collected at Heraldry of the World, while terminology and related charges can be explored in Parker’s A Glossary of Terms Used in Heraldry and through the Heraldry Society. In coats of arms, the horseshoe unites luck with labor, making it an appealing emblem of protection, craftsmanship, and useful strength.
