Motor Yacht A is a superyacht designed by Philippe Starck and engineered by naval architect Martin Francis. It was built by the Blohm + Voss shipyard at the HDW deepwater facility in Kiel. It was ordered in November 2004, and delivered in 2008 at a rumoured cost of US$300 million. With a length of 119 metres (390 ft) and measuring almost 6,000 tonnes, it is one of the largest motor yachts in the world. It is owned by Russian entrepreneur and industrialist Andrey Melnichenko. To avoid seizure by EU authorities, the yacht has been laid up in the United Arab Emirates since 2022.

Philippe Starck is a French industrial architect and designer known for his wide range of designs, including interior design, architecture, household objects, furniture, boats and other vehicles.
