The 2011 Tri Nations Series is 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 is expected that in 2012 Argentina's Pumas will join the series, expanding it to be the "Four Nations".^[1] The 2011 tournament is therefore likely to be the last Tri Nations series with three teams participating.

The 2011 Rugby World Cup is being held in New Zealand between 9 September and 23 October 2011. The 2011 Tri Nations has thus been shortened to include only six games instead of the usual nine. Each team will play the other two countries twice rather than three times.
