 2023–24 Challenge Prince Rainier III | |
The Challenge Prince Rainier III is a domestic football cup in Monaco, featuring teams from across the country. The tournament has been organised annually since 1975 and since then has been known as the premier footballing tournament for amateur teams within the principality.
Because Monaco is not a member of UEFA, there is no qualification for the winners into either the UEFA Champions League, UEFA Europa League, or UEFA Conference League.
