Hadi Choopan, known by his nickname "The Persian Wolf", is an Iranian professional bodybuilder who competes in the men's open bodybuilding division in the IFBB Pro League. Choopan is the former Mr. Olympia, having won the title in the 2022 Mr. Olympia competition.

Mr. Olympia is the title awarded to the winner of the professional men's bodybuilding contest in the open division at Olympia Fitness & Performance Weekend—an international bodybuilding competition that is held annually and is sanctioned by the IFBB Professional League. Joe Weider created the contest to enable the amateur Mr. Universe winners to continue competing and to earn money. The first Mr. Olympia was held on September 18, 1965, at the Brooklyn Academy of Music, New York City, with Larry Scott winning his first of two straight titles. The equivalent female title is Ms. Olympia.
