Jonathan Sexton has been confirmed as the new captain at Leinster.
The 33-year old out-half replaces the retired Isa Nacewa.
Back-row Rhys Ruddock is the province's new vice-captain.
Head Coach Leo Cullen said: “Johnny is a player and person who is always striving to improve and get better and he has driven incredibly high standards during his time at Leinster, where he has become one of the most decorated players in the game.
“He has already carried out the role of captain of the team on a number of occasions and we are very fortunate to be able to announce Johnny as club captain for the 2018/19 season as he is a player that greatly deserves this honour.
“He is hugely excited by the challenge of leading his teammates over the course of the season as we look to maximise the team’s potential.
“Likewise Rhys, we have seen him grow into an outstanding leader at Leinster and indeed he has captained Ireland on tour to Japan and again last season against Fiji and I think that this appointment today is further evidence of that growth.
“You couldn’t get two players that better represent the values and behaviours that we want to be judged on than Johnny and Rhys and I look forward to working even closer with them over the coming months.”
