Anthony Mosse (born 29 October 1964 in Hong Kong) was the standard bearer for New Zealand competitive swimming through the 1980s. He swam at his first Commonwealth Games, in Brisbane, Australia in 1982, when he was 17. Two years later, at the Los Angeles Olympics, he made the final in his two butterfly events.
At the 1986 Commonwealth Games in Edinburgh, Scotland, he won gold and silver and in the same year was second in the 200m butterfly final at the world championships. Mosse developed his career in the United States but continued to swim for New Zealand, gaining a bronze medal at the 1988 Olympics in Seoul, Korea. He rounded out his superlative career when he won the 200m butterfly at the 1990 Commonwealth Games in Auckland.
Mosse gained a BA(Hons) from Stanford University in 1989 and later completed an MBA at the same university. He and his American wife Gail have two children. He is now a merchant banker in San Francisco, but continues to be involved in swimming and is a regular commentator for TVNZ (including Beijing, 2008).
