Hermann III. von Kastl, Count of Kastl, was born circa 1076 to Friedrich I. von Kastl (?-1103) and Berta von Schweinfurt (?-1103) and died before 1125 of assassination. Notable ancestors include Charlemagne (747-814). Ancestors are from France, Germany, Belgium.

Little is known about Hermann. On his brother's death, the family properties were returned to the emperor so Friedrich must have been dead then and cannot have had any legitimate sons.
