Aboriginal breastplates (also called king plates or aboriginal gorgets) were a form of regalia used in pre-Federation Australia by white colonial authorities to recognise those they perceived to be local Aboriginal leaders. The breastplates were usually metallic crescent-shaped plaques worn around the neck by wearer.

Aboriginal people did not traditionally have kings or chiefs. They lived in small clan groups with several elders—certain older men and women—who consulted with each other on decisions for the group. By appointing kings of tribes, and granting them king plates, colonial authorities went against the more collegiate grain of traditional Aboriginal culture.

In the 19th century, king plates were given by numerous communities in various Australian States to esteemed Aboriginal men and women, who were usually elders of their particular tribal or kinship group. The plates were presented to perceived 'chiefs', courageous men and to faithful servants.^[1] There have been suggestions that the presentation of breastplates also had a great deal to do with whether or not the recipient was seen as useful or respected by the white Australian community of the area in question.

The plates were typically made from industrial metals such as brass or iron. A typical format of inscribing the breastplates was to write the recipients name across the upper part of the plate's face, with the title below, sometimes 'King', 'Queen', or 'Chief'. Some particularly distinguished Aboriginal characters are said to have ironically had the royal seal of Queen Victoria engraved somewhere on the plate to add an extra air of prestige. While some Aboriginal people wore their breastplates with pride, others saw them as yet another insult to their culture from the white European settlers.^[2]

The practice of presenting respected Aboriginal leaders with breastplates declined in the post-Federation years,^[3] becoming virtually unheard of by the end of the 1930s.

Little is known about individual Aboriginal people who were awarded breastplates. Some are merely inscribed "King", "Queen", or "Prince", while others are inscribed for some type of service of merit for which they were awarded. There is differing reference to how breastplates were received by Aboriginal people, some wore them proudly, while others destroyed them.

Aboriginal breastplates can be difficult to document and this work is made the more difficult as it is now many decades since they were last worn. Most pre-date living memory, with the majority having been given out between the mid nineteenth and very early twentieth century. Further complicating matters is the change in place names, particularly property names. Many pastoral stations and farms have either been subsumed into larger properties or divided into smaller ones at various times. With this came name changes, with some names disappearing altogether. The bearers of breastplate are important historical figures, however many remain unknown to present and future generations.
