The IRFU and Munster have confirmed that Paul O'Connell will retire from international rugby at the end of the 2015 Rugby World Cup.
The Irish captain will be released from his IRFU and Munster contract once Ireland's participation at the tournament is completed.
O'Connell, who is currently contracted until June 2016, has requested an early release from contract and both the IRFU and Munster have acceded to the request given his exceptional contribution to the sport.
The Limerick man made his senior Munster debut in August 2001 away to Edinburgh and has represented the province on 178 occasions.
With Munster, O'Connell has won two European Cups (2006, 2008), three League titles (2003, 2009, 2011) and a Celtic Cup in 2005.
O'Connell made his Ireland debut against Wales in February 2002 and has won 101 caps for his country. With Ireland, he has won a Grand Slam (2009), led his country to two Six Nations Championship titles (2014, 2015) and claimed four Triple Crowns (2004, 2006, 2007, 2009).
In 2009, O'Connell led the British and Irish Lions Tour of South Africa. A three-time Lions tourist (2005, 2009, 2013) he played in a total of seven Lions Tests and was a member of the Series winning side in Australia in 2013.
Philip Browne, IRFU CEO commented: "Paul has been a fantastic servant to Irish Rugby. Over the course of his 101 Ireland caps to date he has set the standard for the model Irish professional.
"His contribution to Irish rugby is immeasurable in terms of not only driving success on the field but also raising the profile of Irish Rugby around the world.”
Garrett Fitzgerald, Munster CEO commented: "In wishing Paul all the best for the future I would like to acknowledge the outstanding role he has played within Munster.
"Over a 14 year career with the province, Paul has epitomised what it means to wear the red jersey, and through his own hard-work, commitment and leadership he has become an iconic figure in world rugby.
"A truly great ambassador for the province, he has been the standard-bearer of this team for over a decade and everyone around him has reaped the benefits of his professionalism and dedication.
"We would like to think this is not the final chapter in Paul's Munster story, and we would welcome future opportunities to work with him again.”
O'Connell, commented: "I would like to thank Munster and the IRFU for releasing me from my contract at the end of the Rugby World Cup.
"I have been hugely fortunate to play with one of the greatest sporting organisations in the world and as a proud Limerick, Munster and Irishman, I will forever treasure my association with Munster.
"After the World Cup I would like to experience new environments, and it is my genuine hope and ambition that I will have some future involvement with Munster and Irish Rugby.
"I would also like to thank all Munster and Irish fans for their support and I look forward to them showing why they are regarded as the best supporters in world rugby as Ireland travel to the Rugby World Cup in England in September.”
