The last time the prestigious Irish Open was hosted at the K Club, in 2016, McIlroy charged down the final nine with a birdie-par-eagle finish to edge Russell Knox and Bradley Dredge by three strokes.
In doing so, McIlroy added his name to the list of legendary names on the trophy, which includes Seve Ballesteros, Sir Nick Faldo, Padraig Harrington and Colin Montgomerie.
As such, the Northern Irishman is excited to return to the scene of the victory in 2023.
"The Irish Open is a tournament that I grew up not just watching on TV but attending as a kid, seeing all my favourite players there over the years," said the fout-time major winner, as per Sky Sports.
"It's always been such a well-supported event. I've had my fair share of support and great memories at that tournament and going back to The K Club, it's where I've had the most success and I'm obviously excited to get back there.
"The atmosphere was electric during that final round in 2016 and I'm looking forward to seeing the fans out in force at The K Club once again."
McIlroy has enjoyed a stellar year on the golf course, claiming the lucrative FedEx Cup for the third time and then following it up by finishing top of the DP World Tour rankings to clinch his fourth Harry Vardon Trophy.
