Perforated baton, bâton de commandement or bâton percé are names given by archaeologists to a particular type of prehistoric artefact made from antler from Prehistoric Europe, whose function remains debated. The name bâtons de commandement ("batons of command") was the name first applied to the class of artefacts, but it makes an assumption of function, as a ceremonial object or insignia held by leaders. The name bâton percé, meaning "pierced rod", or "perforated baton" (the term used by the British Museum) is a more recent term, and is descriptive of form rather than any presumed function.

Many are decorated with carved or engraved animals, and recently the most usual explanation of their use is that they were used for straightening spears and arrows, and as spear-throwers. Originally they were thought by many to be a symbolic attribute of authority.
