Leinster

History of Leinster 

Originally founded back in 1879, Leinster Rugby is one of Ireland's four professional provincial teams, alongside Munster, Ulster and Connacht.

Leinster's long and prestigious history has seen the club enjoy an impressive array of cup triumphs and league victories in competitions old and new. The team currently competes in the United Rugby Championship, a tournament in which it holds the current record for the most championship wins (10). In addition, the side has also won four European Rugby Champions Cups and one EPCR Challenge Cup. 

Leinster Rugby has been an active provincial team since it was founded in 1879, albeit on an amateur level for over 100 years. As such, in the time before the club officially turned professional in 1995, its sporting history is chiefly around its record in the IRFU Interprovincial Championship - which it has won 22 times in total.

In Leinster Rugby's early professional years, the team saw mixed levels of success. The club was crowned champions in the inaugural season of the defunct Celtic League (now the United Rugby Championship) in the 2001-02 season, but in the years following this, Leinster were dogged by a series of missed opportunities. This included several failed European campaigns and late misses on the final days of the 05/06 and 06/07 seasons.

Another notable event during this time was a brief stint between 2001 and 2004, where Leinster Rugby was renamed 'Leinster Lions'. However, 'Lions' was later dropped from the club's name and the brand and is now only used for marketing purposes.

It's since 2008 that the club has truly established itself as one of the greats on both a domestic and European level. The club’s first European Rugby Champions Cup win came in 2009, and they enjoyed repeated successes in 2011, 2012 and 2018. This achievement has been mirrored in its record 10 titles in the United Rugby Championship. The most recent of these came in the 2025-26 season.

With such a revered and prolific history at all levels, many of the biggest names in the sport have featured in the Leinster rugby squad over the years. In fact, household names such as Johnny Sexton, Brian O'Driscoll and Jamie Heaslip all played for Leinster. 

At present, the Leinster Rugby squad is predominantly made up of Irish internationals. This includes Tadhg Furlong, Andrew Porter, Joe McCarthy, Jamison Gibson-Park and Hugo Keenan.
