Dai Guohong (simplified Chinese: 戴国宏; traditional Chinese: 戴國宏; pinyin: Dài Guóhóng; born September 3, 1977 in Liaoyang, Liaoning) is a retired Chinese swimmer, who specialized in breaststroke and individual medley events. Although she had never competed in any edition of the Olympic Games, Dai held her distinction of being one of the world's top class swimmers in the early 1990s. During her sporting career, she captured more than a dozen medals in breaststroke and individual medley, and also helped the Chinese team demolish a global standard in the medley relay from the FINA World Aquatics Championships in 1994.
