Rory McIlroy's charitable foundation, the Rory Foundation, has raised €951,000 for three children's charities.
Barretstown, the Jack and Jill Foundation and LauraLynn Children's Hospice all benefitted from the Dubai Duty Free Irish Open, held at The K Club this year.
The foundation says each charity will receive €317,000 to go towards specific projects.
Barretstown will direct their funding towards a new dining hall at their Naas campus, while the Jack and Jill Foundation donation will go towards more than 19,800 hours of home nursing care.
LauraLynn Children's Hospice say they will have enough money to provide two clinical nurse specialist salaries, auxiliary expenses and administration for over two years.
Speaking at the announcement, McIlroy said: "While winning the Irish Open this year meant a lot to me, being able to give my prize money to three local children's charities made it all feel much more special."
"I can think of no charities as worthy or deserving of support than Barretstown, the Jack and Jill Foundation and LauraLynn Children's Hospice. I'm so proud of how much my Foundation raised and I'm already looking forward to new projects in 2017."
While Barry Funston, chief executive of the Rory Foundation, added: "Thanks to the events and initiatives that took place during the week of the Irish Open we were able to raise a huge amount of money for three very worthy charities."
"Our hosting of the event really is creating a platform for positive change, rising not only money but awareness of the incredible work being done in the community."
"A gift of time"
CEO of Barretstown Dee Ahearne said: "On behalf of those children and their families, we would like to say a huge Barretstown 'thank you' to Rory and all the team in the foundation whose hard work behind the scenes made the Irish Open and the other events surrounding it such a success."
"The impact this funding will have on the lives of the children with serious illness we serve will be huge."
While the CEO of the Jack and Jill Foundation Jonathan Irwin said: "This €317,000 donation from the Rory Foundation is literally a gift of time to the families under our wing, with every cent being spent directly on the 280 families under our wing and funding 19,813 hours of home nursing care at €16 per hour."
And the LauraLynn Children’s Hospice CEO Sharon Morrow said: " The €317,000 donation we are receiving is beyond generous. It will go towards the development of the LauraLynn@HOME programme, offering hands-on clinical care to children and their families in the home."
"We plan to develop a new symptom management team, spearheaded by two clinical nurse specialists, which will offer choice to families who wish to avail of symptom management care in their home."
