Yves Bouvier (born 8 September 1963) is a Swiss businessman and art dealer best known for his role in the Bouvier Affair that resulted in criminal charges being brought and dismissed against him in France and Monaco by Russian oligarch Dmitry Rybolovlev. He was the president of Natural Le Coultre, an international company specialising in the transportation, storage, scientific analysis, and conservation of works of art, luxurious goods and other collectables.

Bouvier has faced lawsuits filed by Rybolovlev in Singapore, Hong Kong, New York, Monaco, and Geneva since 2015. All legal proceedings, however, have been dismissed by the authorities.

In December 2023 Bouvier and Rybolovlev were reported to have reached an agreement and set aside all of their remaining legal disputes in all jurisdictions.

In September 2017, it emerged that Bouvier was 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. As of 2024, Yves Bouvier was ordered to pay 730 million Swiss francs in unpaid taxes.

Yves Bouvier was born in Geneva, Switzerland, the son of Jean-Jacques Bouvier, owner of Natural Le Coultre, a 150-year-old company specialized in moving and storing goods.

He spent his childhood in Avully, a small village situated near the border with France. He had a sister who was born with a disability and died later in life.

Yves Bouvier developed an early interest in art and dropped out of college to join his father's company in the eighties.

Natural Transports was formed in 1859 as a moving and furniture storage company. It later became Natural Le Coultre in 1901, when Albert-Maurice Natural joined Emile-Étienne Le Coultre to create A. Natural, Le Coultre & Cie. The company's office was located in Geneva. The firm was mainly dealing with commodity deliveries, including fruits, equipment and Red Cross parcels during the First World War.
