The Battle of Lechfeld (10 August 955), perhaps the defining event for holding off the incursions of the Magyars into Central Europe, is a decisive victory by Otto I the Great, King of the Germans, over the Magyar leaders, the harka (military leader) Bulcsú and the chieftains Lél (Lehel) and Súr.

Located south of Augsburg, the Lechfeld is the flood plain that lies along the Lech River.

The battle appears as the "Battle of Augsburg" in Hungarian historiography.

It will be followed up by the Battle of Recknitz in October.
