Michael Kearney will step down from his role as team manager after Ireland's November Test series.
Kearney took over the role from Paul McNaughton in January 2012, but is stepping back to allow the Irish Rugby Football Union (IRFU) plenty of time to plan for the 2019 World Cup.
"It has been a great privilege to work with the national team for the past five years," said Kearney.
"I've witnessed at first hand the incredible work ethic of players and management and the desire to reach world-class standards in everything they do.
"The time was right for me to step down and allow the next team manager time to integrate into the group ahead of the next World Cup."
Kearney managed Ireland on the 2013 tour to North America before remaining in the role under head coach Joe Schmidt.
