Six Nations Rugby is the official organising body, responsible for rugby's greatest annual international Championships and competitions, working in collaboration with its member Unions and Federations; England, France, Ireland, Italy, Scotland & Wales. Each year the six nations compete in rugby's oldest Championship, the Guinness Six Nations, the ground-breaking TikTok Women's Six Nations and the U20s Six Nations Championship. Alongside these competitions are the annual Six Nations Under 18s festivals for men's and women's teams, designed to support the pathway for future rugby stars. Six Nations Rugby is also responsible for the promotion and operations of the Autumn Nations Series; the best of the Southern Hemisphere visiting the Northern Hemisphere each year to take on their counterparts. Fans are at the heart of everything Six Nations Rugby is responsible for, and key to its mission to deliver year round unmissable experiences.
