The 2005 Tri Nations Series, an annual rugby union competition between the national teams of Australia, New Zealand and South Africa, was the tenth in the series. The competition is organised by SANZAR, a consortium of the three countries' rugby federations. This was the last year in which the Tri Nations was contested in its original double round-robin format, with each team playing the others twice.
New Zealand claimed the title with a 31–27 win over South Africa in the penultimate week of the competition; New Zealand's final opponents, Australia, were already unable to catch them and the result put New Zealand above South Africa with the Springboks having played all their matches. The All Blacks also retained the Bledisloe Cup with victory over Australia in both fixtures. The Mandela Challenge Plate between Australia and South Africa was contested outside the Tri Nations.
