Penrith-born Stuart Lancaster has signed a new contract with Leinster.
In a double boost for the Guinness PRO14 club, head coach Leo Cullen has also signed fresh terms.
"Everyone can see that we have benefited from Stuart’s vast experience working within the academy system in England plus, of course, his time with the English national team," CEO Mick Dawson told Leinster's website.
"He has consistently shown his commitment to the Leinster cause and it is a real boost to retain the services of a world-class coach."
While Cullen's contract will see him stay at Leinster until the end of the 2020/21 season, the length of Culgaith man Lancaster's new deal has not yet been revealed.
Last season, under the leadership of Lancaster and Cullen, Leinster claimed the European Champions Cup and PRO14 double.
