The Behsudh (alternatively Besud, Behsud, Behsudi or Basud, Dari:, Behsud) are one of the major tribes of the Hazara people of Hazarajat, central Afghanistan. They inhabit the Markaz Besud and Besud Hisa-i-Awal & Hisa-i-Duwum, Jalrez, Dai Mirdad and Chak districts of Wardak Province, Nawur and Jaghatu Districts of Ghazni province and Panjao and waras Districts of Bamian provence in Afghanistan.
It is claimed that Behsud is a tribe of Mongol, direct descendant of Genghis Khan himself as follow: "Besud branched off the prominent Taichuud (Taijiud) tribe who is the closest kin to and shared the same ancestry, Khamag Mongol Ambaghai Khaan, with Borjigid/Chingisids. Today Besuds, like other Mongol tribes, spread out throughout the territories of former Great Mongol Empire. In Mongolia majority of Besuds live in Gobi-Altai and Bayankhongor provinces."
The 19th century Behsudh chieftain Mir Yazdan Bakhsh was one of the first Hazara chiefs, who tried in vain to unify all Hazaras.
