The National Cup (NC) is an annual Wednesday tournament played in each country each year, pitting every team in Leagues I through V in a seeded tournament to determine the National Champion. Each team is separated by league, and then randomly seeded based on their league, meaning all League I teams will be seeded higher than all League II teams. Teams reseed after each round, meaning the best team will always play the worst team until the final round.
The winner of the National Cup advances to the National Champions Cup (NCC) the next season. In the event that the National Champion advances to the World League, the runner-up of the NC would advance to the NCC.
This is a list of champions for each season of the NC in the USA, and how each of them faired in the National Champions Cup (NOTE: The NCC has only existed since Season 9).
