Players from Co Meath are especially being urged to check their tickets.
The lucky Quick Pick ticket was sold in JR's First Stop store in Ashbourne Town Centre.
Rod Cosgrave, store owner of JR’s First Stop in Ashbourne, said: "I just found out this morning so I've been saying it to everyone who comes into the shop and encouraging them to spread the word.
"It would be fantastic if it was a local but I honestly haven't got a clue who it could be.
"The news is spreading fast so there’s a great buzz about the town now".
The winning EuroMillions Plus numbers were: 07, 18, 24, 37, 50.
