The winning ticket of last night's €14.6 million Lottery jackpot was bought online by a player in Dublin.
The National Lottery said a notification and email has been sent to the player advising them to make contact with the prize claims team.
The winning numbers were 3, 8, 10, 24, 32, 41 and the bonus number was 30.
The total jackpot was €14,674,966 and the winner is the highest online jackpot winner in the history of the game, and the seventh highest single Lotto jackpot winner since the game began over 36 years ago.
It is the first jackpot win of 2024 and the first jackpot win since October when two players in Dublin shared a €7.7m prize.
A spokesperson for the National Lottery said: "As Ireland's newest multi-millionaire, we are advising the winner to make contact with our prize claims team as soon as possible and we will make arrangements for them to visit the Winners Room to collect their cheque."
