Tadhg Furlong has agreed a contract extension with the IRFU until the end of the 2024/25 season.
The 29-year-old Leinster tighthead prop has 52 Irish caps to his name and also started all six Tests when the Lions played New Zealand and South Africa.
The Wexford native, who made his Ireland debut in 2015 against Wales, is widely regarded as one of the best players in the world.
Having signed a one-year contract in May to remain with Leinster until the end of the current season, Furlong has now - following on from his starring role in Ireland's three test wins this month - signed a long-term deal.
"Tadhg has again illustrated his pedigree as one of the best tightheads in world rugby," said IRFU high-performance director David Nucifora said.
"His performances for Ireland and the British and Irish Lions in the past year have been top drawer and we are delighted that he has extended his contract to the end of the 2024/25 season."
Furlong, who featured in all three of Ireland's Autumn Nations Series wins, added: "November was a really positive block for the Ireland squad and it was great to have supporters back in the stadium.
"Ireland and Leinster have started the season well and both squads will be aiming for silverware again this season."
