Ireland international Garry Ringrose has signed a three-year contract with the IRFU which will keep him at Leinster until the summer of 2025.
The 26-year-old has won 37 caps for Ireland since making his debut in 2016 and has since scored 10 tries.
Ringrose was part of the 2018 Grand Slam-winning team - he's also represented Leinster 90 times, scoring 28 tries and winning one Champions Cup and four league titles with the province.
Ringrose said: "Delighted to sign for another three years. It is an exciting time to be involved with Leinster and Ireland.
"Both squads have ambition to be competing for silverware every year and I’m motivated to do whatever I can to contribute"
IRFU High Performance Director, David Nucifora added: "Garry has had a tough road with injuries since the World Cup in Japan but he is a top international player who delivers big performances for Ireland and Leinster.
"He will be an influential figure at both national and provincial level over the coming years."
