The Serbian eagle is a double-headed heraldic eagle, also known as the White eagle, a common symbol in the history of Serbian heraldry and vexillology. The double-headed eagle and the Serbian cross are the main heraldic symbols which represent the national identity of the Serbian people across the centuries, originating from the medieval Nemanjić dynasty. The eagle, defaced with the cross, has been used in the coat of arms of the Kingdom of Serbia from 1882 to 1918 and in contemporary coat of arms of the Republic of Serbia since 2004.

The double-headed eagle is an iconographic symbol originating in the Bronze Age. A heraldic charge, it is used with the concept of an empire. Most modern uses of the emblem are directly or indirectly associated with its use by the late Byzantine Empire, originally a dynastic emblem of the Palaiologoi. It was adopted during the Late Medieval to Early Modern period in the Holy Roman Empire, Albania and in Orthodox principalities, representing an augmentation of the (single-headed) eagle or Aquila associated with the Roman Empire. In a few places, among them the Holy Roman Empire and Russia, the motif was further augmented to create the less prominent triple-headed eagle.
