1999 World Cup was staged primarily in Wales, though Ireland played all their pool games in Dublin. In a play-off, Ireland were beaten 28–24 by Argentina, marking the first time that Ireland failed to reach the quarter-finals. From this nadir, however, Irish rugby improved. The Irish Rugby Football Union converted the four representative provincial sides into de facto club sides, and the formation in 2001 of the Celtic League (now called the Pro14) provided Irish provincial sides with regular competitive rugby. The advent of the new Six Nations format coincided with this Irish resurgence. In 2001, Ireland finished second. Eddie O'Sullivan took over as coach in November 2001 after Warren Gatland was sacked. The 2003 Six Nations Championship saw Ireland lose to England in the Grand Slam decider at Lansdowne Road, ending a home unbeaten run that stretched to 10 tests since September 2002. In the 2004 Six Nations, Ireland finished second overall and won the Triple Crown. In the 2005 Six Nations, Ireland finished in third place.

Ireland won the 2009 Six Nations Championship and Grand Slam, their first Six Nations win since 1985 and their first Grand Slam since 1948. After a draw against Australia and victories against Fiji and South Africa, Ireland ended 2009 unbeaten. In Ireland's final game of the 2010 Six Nations, and the last-ever game at Croke Park, Ireland lost to Scotland 20–23 and failed to win the Triple Crown. Ireland began their 2010 Autumn Tests with a 21–23 loss to South Africa, the first international at the new Aviva Stadium. 2011 to present In the 2011 Six Nations Championship, Ireland lost 22–25 to France in the first Six Nations match to be played at the Aviva Stadium.
