The Braganza Brooch is a gold ornamental fibula that was made in the third century BC by a Greek craftsman for an Iberian client. Since its discovery in unknown circumstances in the nineteenth century, it has belonged to a variety of owners, including various members of the House of Braganza, for which it is named, before being purchased by the British Museum in 2001.

This heavy gold brooch is dominated by the figure of a naked warrior who wears a Celtic helmet and protects himself with a Celtic shield and sword from a hunting dog which jumps up to him. Each end of the fibula is decorated by a dog's head and it once furnished a spring and pin which is now lost. The form, style and technique suggest that it was made in the third century BC by a Greek jeweller for a Celtic patron who lived on the Iberian Peninsula.

Contemporary Iberian brooches were usually made of silver and were often decorated with warriors on horseback accompanied by hunting dogs. In this unique gold version, the craftsman has simplified the hunting scene and added a boar's head, which once served as the sliding catch for the now missing pin. The brooch measures approximately 14 cm long.
