The 2025 Rugby Championship

The 2025 Rugby Championship is a rugby union competition operated by SANZAAR, and will take place from mid-August to the start of October 2025. It will be the fourteenth edition of the annual Southern Hemisphere rugby union competition, featuring the men's national teams of Argentina, Australia, New Zealand and South Africa.

South Africa enter the competition as the defending champions and kick off the tournament against Australia on 16 August. The three traditional unions, also known as the Tri-Nations, announced their 2025 home fixtures in November and December 2024. A notable fixture is set to be played between Argentina and South Africa in the final round at Twickenham Stadium in London, exactly one week after the 2025 Women's Rugby World Cup final. It is the second time a Rugby Championship match has been played at Twickenham Stadium after Argentina played Australia during the 2016 Rugby Championship. It will be the last tournament before the beginning of the Nations Championship, which will see the Rugby Championship move to a biennial basis.
