The 35-year-old won 47 caps and has captained his country twice, against Tonga and Samoa in 2003, since making his Test debut in 1997.

Corrigan played at two World Cups and helped Ireland win the Triple Crown in 2004. His last cap came against France in this year's RBS 6 Nations Championship.

Corrigan will continue to play for Leinster but his decision comes just 24 hours after fly-half David Humphreys announced his retirement from Test rugby.

The prop lost his place in the Ireland side to Marcus Horan after the summer tour to Japan in 2005, but was recalled for a one-off appearance against the French when the Munster player was ruled out through illness.

He did not feature in any of Ireland's other RBS 6 Nations matches or their Triple Crown success.

''This is the right time for me to make this decision from both a personal and professional point of view in advance of the World Cup,'' said Corrigan.

''It has always been a huge honour for me to wear the Ireland jersey, none more so then over the last six years where the fortunes of both the team and Irish Rugby have continued to rise.

''Although every professional sportsman wishes they could continue forever, I have been lucky to have a career playing the game I love.''

Humphreys announced his retirement from Test rugby the previous day, though the 34-year-old fly-half will continue to play for Ulster next season.

''Both David and Reggie have been wonderful servants to the Ireland team and rugby in general,'' said Ireland coach Eddie O'Sullivan.

''During my time with the national team, both players were senior members of the squad and natural leaders, with both of them captaining the side.

Davids wish to spend more time with his young family is understandable and I wish him the very best for his career plans.

''He was one of the most gifted players to wear the green jersey and played a key part in the success of the Ireland team over the last number of years. I am sure that he will continue to be a strong influence with Ulster.

''Reggies natural athleticism and strength were massive attributes to the team. He was a key member of the side and an integral part of our first Triple Crown win in 19 years in 2004.

''I believe that Reggie will be remembered as one of Irelands great front row forwards.''
