The National Lottery is appealing to players in Waterford to check their tickets.
It's after the winning ticket in last night's EuroMillions Plus draw was bought in Waterford.
The ticket is worth €500,000.
The winning Quick Pick ticket was bought yesterday at the Maxol/Mace filling station on the Cork Road on the outskirts of Waterford City.
This is the 25th EuroMillions Plus top prize of €500,000 won in Ireland so far this year. The all-important winning numbers from last night's EuroMillions Plus draw are 05, 23, 32, 37 and 44.
It's the second win in Waterford in recent weeks, the winner of the Lotto Plus 1 game was sold in Tramore. That ticket was worth €1 million.
A spokesperson for the National Lottery said: "While there was no winner of last night's EuroMillions jackpot of €144 million, more than 62,000 players in Ireland were prize winners so we are calling on everyone across the country to check their tickets.
"However the biggest winner of the night was our €500,000 EuroMillions Plus winner in Waterford.
"If you are this lucky winner please sign the back of the ticket and get in touch with the National Lottery claims team on 1800 666 222 or email [email protected] and we will make arrangements for you to get your prize".
