Leinster

Leinster Rugby (Irish: Rugbaí Laighean) is one of the four professional provincial rugby teams from the island of Ireland and the most successful Irish team both domestically and in European competition. They compete in the Pro12 and the European Rugby Champions Cup. The team represents the Irish Rugby Football Union (IRFU) Leinster Branch, which is one of four primary branches of the IRFU and is responsible for rugby union throughout the geographical Irish province of Leinster.

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.

Leinster turned professional along with its fellow Irish provinces in 1995 and has competed in the Pro12 (formerly known as the Celtic League and the Magners League) since it was founded in 2001, having previously competed in the annual Irish interprovincial championship. Leinster "A" competes in the British and Irish Cup. Leinster have four times been Pro12 champions and three times champions of Europe.
