The America's Cup, informally known as the Auld Mug, is a trophy awarded in the sport of sailing. It is the oldest international competition still operating in any sport. America's Cup match races are held between two sailing yachts: one from the yacht club that currently holds the trophy and the other from the yacht club that is challenging for the cup. There is no fixed schedule, with matches held several years apart on dates agreed between the defender and the challenger. The most recent America's Cup match took place in March 2021.

The 12 Metre class is a rating class for racing sailboats that are designed to the International rule. It enables fair competition between boats that rate in the class whilst retaining the freedom to experiment with the details of their designs. The designation "12 Metre" does not refer to any single measurement on the boat, and is not referencing the vessels overall length, rather, measures the sum of the components directed by the formula which governs design and construction parameters. Typically 12 Metre class boats range from 65 to 75 feet in length overall; they are most often sloop-rigged, with masts roughly 85 feet tall.

The 1962 America's Cup, the second to be sailed in 12-metre yachts, marked the first challenge for the Cup from a country other than Great Britain or Canada, and was the first challenge from a country in the southern hemisphere.
