The National Lottery is urging Dubliners to check their Euromillions tickets.
It's after someone in the capital won €2.5 million in last night's draw.
They were one of eight buyers across the continent to match five numbers and a "lucky star".
The maxed-out jackpot of €190 million still hasn't been claimed.
“While this lucky player just fell short of the whopping €190 million EuroMillions jackpot, €2,521,015 is still a huge amount of money," National Lottery spokesman Fran Whearty said.
"We are encouraging all of our players in Dublin to check their tickets carefully and if you do happen to be this lucky ticketholder please do keep the ticket safe, sign the back of it and contact our prize claims team," he said.
If the main jackpot isn't won on Tuesday by someone who matches all six numbers, it will be awarded to winners at lower prize tiers.
