Barisan of Ibelin (
French: Barisan d'Ibelin; died 1150) was an important figure in the
Kingdom of Jerusalem, and was the founder of the
Ibelin family. His name was later written as "Balian" and he is sometimes known as Balian the Elder, Barisan the Old or Balian I.
Barisan's origins are obscure. The Ibelins later claimed to be descended from the viscounts of Chartres, but according to

 That year, Barisan was also present at the
