Rory McIlroy, Darren Clarke and McDowell will share Irish Open host role
Paul McGinley will be Irish Open host in 2019 as the event follows the British Masters model which has seen different players fill the role.
Rory McIlroy's charitable foundation has hosted the last three Irish Opens.
The Ulsterman's foundation will have the role again this year at Ballyliffin before McGinley hosts the 2019 event.
Major champions Darren Clarke, Padraig Harrington, Graeme McDowell and McIlroy have committed to undertaking the position over the next number of years.
The precise future rotation of the host role will be confirmed over the coming months along with the 2019 venue.
Major winners Clarke, Harrington and McDowell, along with 2014 European Ryder Cup captain McGinley, expressed delight at being asked to host the event.
Clarke said: "Everyone has seen what a success the British Masters has become with Ian (Poulter), Luke (Donald), Lee (Westwood) and Justin (Rose) all hosting the event.
"I think it's great that we have Rory, Graeme and myself from Northern Ireland and then Paul and Padraig from the South.
"There will be a natural rotation of the tournament and I'm sure there will be a fair bit of competition between the lads to see who can put on the biggest and best tournament."
Harrington and McDowell spoke of how the role will benefit their charities with the 2010 US Open winner's foundation raising money for children's medical research in Ireland and the US.
