Eine Atomuhr ist eine Uhr, deren Zeittakt aus der charakteristischen Frequenz von Strahlungsübergängen der Elektronen freier Atome abgeleitet wird. Die Zeitanzeige einer Referenzuhr wird fortwährend mit dem Taktgeber verglichen und angepasst. Atomuhren sind derzeit die genauesten Uhren und werden auch primäre Uhren genannt.
