Olivier Saminadin (born 6 September 1977) is a French swimmer from New Caledonia. Due to New Caledonia's status as an overseas territory of France, and its current lack of official recognition by the International Olympic Committee, Saminadin (like other swimmers from New Caledonia, such as Diane Bui Duyet), swims for New Caledonia in regional (Pacific) competition, and for France in continental and above championships. He won the inaugural 400 I.M. title at the first French Short Course Championships in January 2005.
