Fasces ( /ˈfæsiːz/, a plurale tantum, from the Latin word fascis, meaning "bundle") are a bundle of wooden sticks with an axe blade emerging from the center, which is an image that traditionally symbolizes summary power and jurisdiction, and/or "strength through unity". Fasces frequently occur as a charge in heraldry, and should not be confused with the related term, fess, which in French heraldry is called a fasce.

The traditional Roman fasces consisted of a bundle of birch rods, tied together with a red leather ribbon into a cylinder, and often including a bronze axe (or sometimes two) amongst the rods, with the blade(s) on the side, projecting from the bundle. They were carried by the lictors who accompanied the magistrates. The axe often represents the power over life or death through the death penalty, although after the laws of the twelve tables, no Roman magistrate could summarily execute a Roman citizen. It was used as a symbol of the Roman Republic in many circumstances, including being carried in processions, much the way a flag might be carried today.
