Employees at the Dublin Airport Authority (DAA) raised €210,000 for three Irish charities last year.
The three charities - Special Olympics Ireland, the Jack & Jill Foundation and Cystic Fibrosis - were each presented with a cheque for €70,000.
The fundraising efforts during 2014 means that DAA staff have donated more than €1.5m to 12 Irish charities over the past nine years.
DAA chief executive Kevin Toland said the money raised will make a difference to peoples lives.
"I am immensely proud of the continuing support and passion of DAA staff in raising this massive sum of money for charity," Mr Toland said.
"Since our charity programme started 12 Irish charities have received significant donations to the total value of €1.5m over a nine-year period. This truly is a phenomenal sum of money doing a lot of good for Irish charities."
Speaking at the cheque presentation, Jonathan Irwin, founder and chief executive of Jack & Jill, said the charity was delighted to be selected as one of the beneficiary charities last year.
"The €70,000 raised for Jack & Jill will generate 4,375 hours of home nursing care for our families nationwide," Mr Irwin said.
Over the course of 2014 a wide variety of events took place with DAA employees, families and friends getting involved to support the three charities.
