The Gurjara Pratihara (Sanskrit: गुर्जर प्रतिहार, Gurjara Pratihâra), often simply called Pratihara Empire, was an imperial Indian dynasty that ruled much of Northern India from the 6th to the 11th centuries. At its peak of prosperity and power (c. 836–910), the Gurajara-Pratihara Empire rivaled or even exceeded the Gupta Empire in the extent of its territory.

Kannauj was the capital of imperial Gurjara Pratiharas. The Gurjara Pratihara rulers in the tenth century was entitled as Maharajadhiraja of Āryāvarta (i.e. Lords of Northern India).

The word "Pratihara" means protector or "who takes over the enemy/opponent" and was used by the Gurjara-Pratihara rulers as self-designation.It is derived mainly from buddhist term "Pratiharya" wich is quoted in many buddhist sutra, as title awarded to them for defending the vedic realm of Aryavarta . The Pratihara rulers claim descent from the Hindu mythological character Lakshmana, who had performed the duty of a gaurdian ("pratihara") for his elder brother Rama. They were thus Suryavansh dynasty according to traditional Indology.
