Yves Bouvier (born 8 September 1963 in Geneva, Switzerland) is a Swiss businessman and art dealer best known for his role in the Bouvier Affair that resulted in criminal charges being brought against him in France and Monaco. He was the president of Natural Le Coultre, an international company specialized in the transportation, storage, scientific analysis, and conservation of works of art, luxurious goods and other collectibles. In September 2017, it emerged that Bouvier is under criminal investigation by Swiss authorities amid allegations that he may have evaded more than 100 million euros in taxes related to his cross-border art dealings. In February 2018, meanwhile, the Geneva Prosecutor reportedly opened a new criminal investigation into Bouvier relating to an indictment on charges of fraud.
