Alinghi was the winning syndicate from Switzerland at the America's Cup in 2003. Their yacht was identified and christened by its sail number: SUI-64.

"Alinghi" is a made-up name, created by the syndicate's founder Ernesto Bertarelli. Bertarelli had raced several smaller yachts named Alinghi previously, but 2003 was his first attempt at the America's Cup. In order to maximize his chance of success, the yacht was developed by the Ecole Polytechnique Federale de Lausanne specifially for the race and he hired the best in the business: Russell Coutts. Coutts had already won the America's Cup for New Zealand in 1995 and he successfully defended for New Zealand in 2000. Along with Coutts came several other important Kiwi sailors, not the least of which was Brad Butterworth. Bertarelli himself served as Navigator during the racing.
