2023 Season
The 2023 Rugby Championship was the eleventh edition of the annual southern hemisphere competition, involving Argentina, Australia, New Zealand and South Africa.
The competition was operated by SANZAAR, a joint venture of the four countries’ national unions, and known for sponsorship reasons as The Castle Rugby Championship in South Africa, The Fortinet Rugby Championship in New Zealand, The eToro Rugby Championship in Australia, and The Zurich Rugby Championship in Argentina.
As in previous Rugby World Cup years, the tournament was reduced, with each nation only playing each other once as part of the Championship.
New Zealand retained the title, the 20th time they won the title.
