The Oceania Rugby Under 20 Championship is an international rugby union competition organised by Oceania Rugby, which is the regional governing body for rugby in Oceania. It is contested by men's junior national teams with an under-20 age requirement, and played as two tournaments: the Oceania Championship for teams that qualify for the World Championship; and the Oceania Trophy for teams aiming to compete in the World Rugby U20 Trophy.

The Rugby Championship, formerly known as the Tri Nations Series (1996–2011), is an international rugby union competition contested annually by Argentina, Australia, New Zealand, and South Africa. These are traditionally the four highest ranked national teams in the Southern Hemisphere; the Six Nations is a similar tournament in the Northern Hemisphere.
