Olivier Boulay is a French automobile designer.
Boulay became well-known for his participation in designing the Maybach 57 and 62. However, he was also responsible for the exterior and interior of the generation II Subaru Legacy.
Boulay headed the design department at Mitsubishi Motors Corporation during a period when DaimlerChrysler actively worked with the company. However, the Mitsubishi Grandis was the only car released during the time that bore fruit of Boulay's influence. The design of the Mitsubishi Colt, released earlier, had been largely locked down by the time Boulay arrived. When DaimlerChrysler announced it plans to terminate its relationship with Mitsubishi, Boulay also left the company.
