The official website of Leinster Rugby with news, match reports, player profiles, merchandise, ticket and hospitality information. Leinster play their home games primarily at the RDS Arena, although larger games are played in the Aviva Stadium when the capacity of the RDS is insufficient. Before moving to the RDS in 2005, Leinster's traditional home ground was Donnybrook Stadium, in Dublin 4. The province plays primarily in blue and the team crest features a harp within a rugby ball, the harp being taken from the flag of Leinster.

Official site for the annual international rugby union competition involving six European sides: England, France, Ireland, Italy, Scotland and Wales. The Six Nations is the successor to the Home Nations Championship (1883–1909 and 1932–39), played between teams from England, Ireland, Scotland and Wales, which was the first international rugby union tournament. With the addition of France, this became the Five Nations Championship (1910–31 and 1947–99), which in turn became the Six Nations Championship with the addition of Italy.
