The Worldwide Club Cup (sometimes known as the Random Club Cup) is an international association football tournament for clubs held in the Southern Arc Islands, organized mainly by the Southern Arc Islands Football Association.

The Worldwide Club Cup is a parallel tournament to the Worldwide Cup; the competition is always held in the Southern Arc Islands, and most of the participating teams are randomly selected; though, under the current format, there are always two Southern Arc clubs: the winners of the previous year's First Division and Grand Football Cup, respectively.

The tournament was created in late 2014, and the first edition, the 2015 Worldwide Club Cup, was held in January 2015. It featured a total of six teams, including two clubs from the Southern Arc Islands; namely, the winners of the 2014 editions of the First Division and the Grand Football Cup.
