The Migration Period sword was a type of sword popular during the Migration Period and the Merovingian period of European history, particularly among the Germanic peoples. It later gave rise to the Carolingian or Viking sword type of the 8th to 11th centuries AD.

A sword is an edged, bladed weapon intended for manual cutting or thrusting. Its blade, longer than a knife or dagger, is attached to a hilt and can be straight or curved. A thrusting sword tends to have a straighter blade with a pointed tip. A slashing sword is more likely to be curved and to have a sharpened cutting edge on one or both sides of the blade. Many swords are designed for both thrusting and slashing. The precise definition of a sword varies by historical epoch and geographic region.
