Leo Cullen to step down as Leinster head coach in 2027 after 12 years; coaching search begins

Announcement

Leo Cullen announced on Monday that he will step down as Leinster head coach when his contract expires at the end of the 2026/27 season. The 48-year-old confirmed the decision via a Leinster press release, citing the timing as right after 12 years in the role and 32 years since he first represented the province as a schools player.

By the end of next season, in 2027, I will have been in my current job for 12 years. It'll also be 32 years since I first represented Leinster as a Schools player! So, I think the timing will be right for me to move on to a new challenge.

Leinster Rugby, in collaboration with the IRFU, will immediately begin a formal recruitment process for his replacement. Cullen is committed to honouring his contract and will continue to lead the team until June 2027.

Legacy and achievements

Cullen's head-coaching record includes six league titles (Pro12, Pro14, URC), the latest coming in Friday's 36-7 victory over the Bulls at Croke Park. He also guided Leinster to the 2018 Champions Cup, becoming the first man to captain and coach the province to European glory. His overall win rate across both competitions exceeds 72%.

An unbelievable legacy to Leinster rugby.

RTÉ analyst Bernard Jackman noted that despite recent Champions Cup final disappointments, Cullen's consistency has been phenomenal. Leinster supplied 26 players to Ireland's Six Nations squad and 18 to the initial Nations Championship squad during his tenure.

Champions Cup heartbreak

While Leinster dominated the domestic league, Cullen's reign is marked by five Champions Cup final defeats since that 2018 triumph. The most recent was a 41-19 loss to Bordeaux-Begles in Bilbao in May. Leinster also lost deciders to Saracens (2019), La Rochelle (2022, 2023), and Toulouse (2024), as well as a semi-final to Northampton Saints.

Succession speculation

Potential candidates include Ronan O'Gara, Noel McNamara, Joe Schmidt, Simon Easterby, Johnny Sexton, Felipe Contepomi, and Stuart Lancaster. Former Leinster player Shane Byrne backed O'Gara, calling it "one of the most sought after jobs in club coaching rugby in the world."

Why not? He has to go somewhere. If you look at the international scene at the moment for him, you would expect that that's the step he would like to make sooner rather than later.

Senior coach Jacques Nienaber is expected to return to South Africa to help the Springboks target a third straight World Cup in 2027, creating a vacancy for at least one key assistant.

Reaction

Leinster CEO Shane Nolan praised Cullen's achievements, highlighting seven trophies in 11 years and his influence as a coach and leader. Byrne also emphasised Cullen's role in developing young talent and creating squad depth that "has essentially been the backbone of the Irish setup for years."

Leo has been a great player, coach and leader for Leinster and will always be held in the highest regard by anyone that has ever been fortunate enough to work with him.

Cullen will have one more season to chase a fifth Champions Cup star, with the 2027 final scheduled for Lyon.
