Choi Duk-hoon (also Choi Deok-hun, ; born March 5, 1976, in Seoul) is a retired amateur South Korean Greco-Roman wrestler, who competed in the men's middleweight category. He produced a remarkable tally of three career medals, including a gold in the 74-kg division at the 2003 Asian Wrestling Championships in Delhi, India, and also finished tenth at the 2004 Summer Olympics, representing his nation South Korea. Having worked as a full-time employee for Sung Shin, Choi trained throughout his sporting career as a member of its wrestling team under head coach Bang Dae-du.
Choi highlighted his sporting career at the 2003 Asian Wrestling Championships in Delhi, India, where he captured a gold medal over India's Sanjay Kumar in the 74-kg division with a comfortable 7–0 decision.
At the 2004 Summer Olympics in Athens, Choi qualified for the South Korean squad, as a 28-year-old, in the men's 74 kg class. Earlier in the process, he placed third in the same class at the Asian Championships in Almaty, Kazakhstan to guarantee a spot on South Korea's Olympic wrestling team. He lost his opening match 2–6 to two-time reigning Olympic champion Filiberto Azcuy of Cuba, but bounced back to oust Poland's Radosław Truszkowski with a challenging 6–1 verdict. Placing second in the prelim pool and tenth overall, Choi failed to advance to the quarterfinals.
