Common card · No. 354421

The All-Ireland League (AIL), known for sponsorship reasons as the Energia All-Ireland League, is the national league system for the 50 senior mens rugby union clubs in Ireland, covering both the Republic of Ireland and Northern Ireland. The league was inaugurated in the 1990–91 season. The league is the second-highest level of rugby union in Ireland, and the highest amateur level. Professional teams representing the four provinces of Ireland play in the United Rugby Championship. Division 1 sides may field no more than two professional players in their matchday sides, and only one may be a forward. Division 2 sides may not field professional players. Foreign professional players may not play in the League. Cork Constitution, the inaugural winners, are the only club to have retained top division status since the inception of the league.
