Isembart or Isembard was the count of Barcelona, Empúries, and Roussillon and margrave of Septimania together with Aleran from 849 or 850 to 852.
He was the son of Garí of Burgundy, count of Autun.
He was named at the assembly of Narbonne in 849. He fought, with Aleran, against William, son of Bernat of Septimania, to consolidate the territory for the Empire.
In 851 or 852, Aleran died and he began reigning alone until the appointment of Odalric within a year.
