Welsh rugby union system

The Welsh rugby union system, or WRU National League system, refers to the hierarchically interconnected league system for rugby union in Wales that in the 2024–25 season consisted of 30 leagues in up to 298 teams. Four Welsh rugby teams sit above the league system as participants in the United Rugby Championship, a professional trans-national rugby union league featuring several teams from Ireland, Wales, Scotland, Italy, and South Africa. The four professional Welsh teams also compete in European cup competitions such as the European Rugby Champions Cup and the EPCR Challenge Cup.
