In heraldry, an augmentation is a modification or addition to a coat of arms, typically given by a monarch as either a mere mark of favour, or a reward or recognition for some meritorious act. The grants of entire new coats by monarchs as a reward are not augmentations, but rather grants of arms, and an augmentation mistakenly given to someone who did not have a right to a coat would be nugatory.

The coat of arms of Scotland, colloquially called the Lion Rampant, is the coat of arms historically used as arms of dominion by the monarchs of the Kingdom of Scotland, and later by monarchs of Great Britain and the United Kingdom. The coat of arms, or elements from it, are also used in heraldry to symbolise Scotland in general. The arms consist of a red lion surrounded by a red double border decorated with fleurs-de-lis, all on a gold background. The blazon, or heraldic description, is: Or a lion rampant Gules armed and langued Azure within a double tressure flory-counter-flory of the second.
