Bozorgmehr-e Bokhtagan ( Middle Persian: Wuzurgmihr ī Bōkhtagān), also known as Burzmihr, Dadmihr and Dadburzmihr, was a Iranian nobleman from the Karen family, who served as minister of the Sasanian king Kavadh I (498-531), and later as Grand Vizier under his son Khosrau I (reign 531–579), and then as spahbed under Hormizd IV. According to Persian and Arabic sources, he was a man of "exceptional wisdom and sage counsels" and later became a characterisation of the expression. His name appears in several important works in Persian literature, most notably in the Shahnameh. The historian Arthur Christensen has suggested that Bozorgmehr was the same person as Borzūya the physician, but historigraphical studies of post-Sassanid Persian literature, as well as linguistic analysis show otherwise. However, the word "Borzūya" can sometimes be considered a shortened form of Bozorgmehr.
