The Kabars (Gr. Kabaroi) were a confederation of three Khazar tribes that rebelled against the authority of the Khazar khagan in the 9th century. The word itself is believed to derive from a Turkic word meaning "rebel."

The Kabars joined the proto-Magyar migration from the steppes of the Ukraine to the Danubian Steppes of modern Hungary, assisting the Magyars in conquering Pannonia. Many Kabars settled in the Bihar region of the later Kingdom of Hungary and Transylvania. Some people believe that the character recorded by Gesta Hungarorum as lord Marot and his grandson Menumorut, dux of Biharia, were of Kabar descent. One of the names on the Kievian Letter is "Kiabar", which may suggest that Kabars settled in Kiev as well.

The Kabars eventually assimilated into the general Magyar population, leaving scattered remains and some cultural and linuistic imprints. Some scholars believe that the Szekely are their descendents.
