Nathan James Wilmot (born 13 December 1979) is a sailor, and a member of the Australiansailing team. He has won five world titles along with teammate Malcolm Page in the 470 class. They also won the Olympic test event in Qingdao in 2007 and were considered favourites to win the 470 event at the 2008 Summer Olympics.
In the Beijing Olympic games they won convincingly on points leading into the medal race which they only had to finish to win first place. They won the finale race which secured them Olympic gold. They have been now classified as the most successful 470 competitors in history.
Although successful in the dinghy classes, he is an established ocean-racing yachtsman.
Wilmot comes from a sailing family. His father competed at the 1984 Summer Olympics and his uncle at the 1988 Summer Olympics. Uncle Hugh Treharne was tactician on the America's Cup syndicate, Australia II in 1983.
