The 2011 Tri Nations Series was the sixteenth annual Tri Nations rugby union series between the national rugby union teams of New Zealand, Australia and South Africa, respectively nicknamed the All Blacks, Wallabies and Springboks. It was also the last series in which only these three teams participated. In 2012, Argentina's Pumas joined this competition, which was rebranded as The Rugby Championship. This made this series the last under the Tri Nations name until 2020, when South Africa withdrew due to the COVID-19 pandemic.
The 2011 Rugby World Cup was held in New Zealand between 9 September and 23 October 2011. As a result, the 2011 Tri Nations was shortened to include only six games instead of the usual nine. Each team played the other two countries twice rather than three times. Australia won the series for the first time in ten years.
