A Limerick EuroMillions player has won €500,000 with a ticket bought in Thomondgate in the city.
The National Lottery has appealed for players to check their tickets from last night's draw.
The winning numbers from last night's EuroMillions Plus draw are: 11, 12, 15, 32 and 44.
The winning quick pick ticket was sold at a Circle K filling station down the road from Thomond Park rugby stadium.
The store is located between the stadium and Thomond Bridge over the River Shannon.
This is the 19th EuroMillions Plus top prize of half a million won in Ireland so far this year, with all 19 winners sharing €9.5m on this game alone.
"We are appealing to all EuroMillions players in Limerick, specifically those who maybe stopped in the Thomondgate area for fuel yesterday, to check those tickets very carefully," said a spokesperson for the National Lottery.
"If you have matched all five of the above numbers contact our prize claims team on 1800 666 222 or email firstname.lastname@example.org and we will make arrangements for you to collect your prize."
There was no winner of last night's jackpot of €38,953,665, but more than 57,000 players in Ireland won prizes, said the National Lottery.
