Dupont polled 26 percent of the 138,000 fans who voted, adding the award to his successes of 2020 and 2022 to become only the second player alongside Brian O'Driscoll to complete a hat-trick of wins.
Also on the shortlist were his Les Bleus' team-mates Thomas Ramos and Damian Penaud and Irelands Caelan Doris, Hugo Keenan and Mack Hansen.
