There was just one winner of the €15 million prize but it is not yet known which county the winning ticket was sold.
Speculation continues on whether the ticket was bought by an individual or a syndicate.
The winning numbers were 16, 18, 26, 38 and 44. The lucky stars were 8 and 10.
This is the third Irish win since June of last year. It would appear that the luck of the Irish is alive and well.
Limerick woman Dolores McNamara was the biggest EuroMillions winner in Ireland with a jackpot of €115 million in 2005.
The mum of six had made the impulsive ticket purchase while buying phone credit on her way to her local bar.
Within a month, sales of the Euromillions had doubled in Ireland as a result of Ms McNamara's win.
