Sevar (Bulgarian: Севар) was a ruler of Bulgaria in the 8th century.

The Nominalia of the Bulgarian khans states that Sevar belonged to the Dulo clan and ruled for 15 years. According to the chronology developed by Moskov, Sevar would have reigned in 721–737. Other chronologies place his reign in 738–754. According to historians such as Steven Runciman and David Marshall Lang, Sevar was the last ruler of the Dulo dynasty and with Sevar died out the lineage of Attila the Hun.^[1][2]

It has been suggested that Sevar‘s name is derived from Persian Ziwar (adornment).^[3] Although initially a female name, it could also serve as a component of male names, as suggested by Chuvash pre-Christian name Aksĕver.^[3] Another etymology of Aksever would be from the Turkic word Ak (white), and Sever (to like) which has its roots in the Oghur Volga Bulgar word Sev or Sav in Chuvash, thereby the name Sevar could also be of Turkic etymology.^[4]
