The Bledisloe Cup is a rugby union competition between the national teams of Australia and New Zealand that has been competed for since the 1930s. The frequency at which the competition has been held and the number of matches played has varied, but as of 2016, it consists of an annual three-match series, with two of the matches also counting towards The Rugby Championship. New Zealand have had the most success, winning the trophy for the 46th time in 2017, while Australia have won 12 times.

The 2018 Rugby Championship will be the seventh edition of the expanded annual southern hemisphere Rugby Championship, featuring Argentina, Australia, South Africa and New Zealand. The competition is operated by SANZAAR, a joint venture of the four countries' national unions.
