It comes after a prize worth €500,000 was sold at a filling station near Thomond Park rugby stadium.
Co Limerick is home to one of the biggest ever Euromillions winners, Dolores McNamara, who won €115 million in 2005.
This winning Quick Pick ticket was bought at the Circle K Thomond service station in Thomondgate, Co Limerick.
The winning numbers from Friday night’s EuroMillions Plus draw are: 11, 12, 15, 32 and 44.
A National Lottery spokesman appealed to people in the Limerick area, particularly those who stopped for fuel, to check their tickets.
“Officially it may have been the last day of summer yesterday but for one lucky ticketholder in Limerick, it’s going to be sunny for a long time as they scooped the EuroMillions Plus top prize of €500,000.
“In fact this is the 19th such winner we’ve had so far in 2020.
“We are appealing to all out EuroMillions players in Limerick, specifically those who maybe stopped in the Thomondgate area for fuel yesterday, to check those tickets very carefully,” said the spokesman.
