Peter O'Mahony has signed a new two-year contract with the IRFU, which will keep him at Munster until 2023.
The 31-year-old made his Ireland debut in the Six Nations against Italy in 2012 and has gone on to win 74 caps.
O'Mahony has represented Munster on 141 occasions.
The Corkman was also part of the Lions tour in 2017 and captained them in the opening Test of the series against New Zealand.
In a statement on the Munster website, O'Mahony said: "It’s a huge privilege to sign on with the province and country I’ve grown up in and dreamed of playing for. It’s been something I’ve been very open about saying from day one and its very pleasing to be able to continue the journey for two more years.
“There’s a huge amount of responsibility that comes with representing both teams and I understand how much pressure there is to deliver silverware, however, I am incredibly enthusiastic on the position and competitiveness of both Munster and Ireland and I look forward to hopefully contributing to both, to succeed in delivering that success on the pitch.”
