Rulon Gardner is an American retired Greco-Roman Olympic Gold Medalist wrestler. He attributes his strength to the physical labor that he performed growing up and working on the family's dairy farm in Wyoming.

He competed at the 2000 and 2004 Olympics and won the gold medal in 2000, defeating Russia's Aleksandr Karelin in the final. Karelin was previously unbeaten for 13 years in international competition. Gardner won a bronze medal at the 2004 Games. In 2005, Gardner published his autobiography, Never Stop Pushing: My Life from a Wyoming Farm to the Olympic Medals Stand, in which he describes his Greco-Roman wrestling career, his academic struggles and an account of his near-death experience when stranded after a snowmobile accident. He is currently making his profession as a motivational speaker, often appearing as a keynote presenter and event host. He has appeared at corporate events, celebrity golf tournaments, trade shows, and conventions. He also has licensing deals, as well as print and television endorsements.

In January 2011, he was announced as a contestant on season 11 of the American reality television show, The Biggest Loser. After 16 weeks on the show, Gardner had lost 173 pounds.
