The Quilter Nations Series is the modern name for the autumn international rugby tests that feature the Ten international sides including the Six Nations teams (England, France, Ireland, Italy, Scotland, Wales) taking on major Southern Hemisphere powers (notably New Zealand, South Africa, Australia, Argentina) and occasionally additional strong teams like Fiji, Japan, and Georgia. The series ran as the Autumn Nations Series and was rebranded with Quilter as the title sponsor starting in 2025, making the event officially the Quilter Nations Series for that year and beyond. The intent is to provide high-profile November internationals, act as a global showcase outside the Rugby World Cup, and help teams prepare for future campaigns while influencing world rankings and visibility for participating nations.

Key points

• History and scope: The event evolved from the traditional November test window into a structured, repeatable autumn series featuring northern-hemisphere nations against top southern-hemisphere sides, with expansions to include other competitive nations over time.

• Format and timing: Typically played over several weekends in November, with individual tests that count toward world rankings and preparation for broader competitions. There is no single knockout tournament winner; the value lies in matchups, exposure, and ranking impact.

• Sponsorship and branding: Quilter joined as title partner from 2025, rebranding the series as the Quilter Nations Series, signaling a long-term sponsorship and renewed branding for the autumn internationals.

• Notable participating teams: The series features Six Nations nations on one side and top-tier teams from the Rugby Championship or other strong nations on the visiting side, delivering high-profile clashes such as England vs Australia and France vs South Africa-type fixtures.
