Bozorgmehr-e Bokhtagan (Middle Persian: Wuzurgmihr ī Bōkhtagān), also known as Burzmihr, Dadmihr and Dadburzmihr, was an Iranian sage and dignitary from the Karen family, who served as minister (wuzurg framadār) of the Sasanian king (shah) Kavad I (r. 498–531), and the latter's son and successor Khosrow I (r. 531–579). He also served as the military commander (spahbed) of Khwarasan under Khosrow I and his successor Hormizd IV (r. 579–590). According to Persian sources, Bozorgmehr 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 Book of Kings"). The historian Arthur Christensen has suggested that Bozorgmehr was the same person as Borzuya, but historiographical studies of post-Sasanian Persian literature, as well as linguistic analysis shows otherwise. However, the word "Borzuya" can sometimes be considered a shortened form of Bozorgmehr.
