Impalement is a heraldic practice in which two coats of arms are combined in one shield to denote a union. The impaled shield is bisected in pale, that is by a vertical line, with each half of the shield displaying one coat of arms. Most often the practice is used to denote the union of a husband and wife in marriage, but impalement is also used to display unions with an ecclesiastical office, academic position, government office, or mystical union.

Heraldry is a discipline relating to the design, display and study of armorial bearings, as well as related disciplines, such as vexillology, together with the study of ceremony, rank and pedigree. Armory, the best-known branch of heraldry, concerns the design and transmission of the heraldic achievement. The achievement, or armorial bearings usually includes a coat of arms on a shield, helmet and crest, together with any accompanying devices, such as supporters, badges, heraldic banners and mottoes.
