“Someone just matched all numbers & stars on tonight’s draw winning a massive €175,475,380 and set a new record for the biggest win in National Lottery history.”
Five other tickets won £275,601 (€317,493).
National Lottery chief executive Dermot Griffin said the shop where the ticket was bought would not be revealed for a few days as procedures had to followed.
“We are advising our players to check their tickets and if they are the winner sign the back of the ticket, keep it safe, and contact National Lottery HQ and we will guide you through the claims process,” he said.
“Whilst this is a massive win it can come as a shock to a player and we advise them to stay calm, get good independent legal and financial advice and contact us as soon as they can.”
He added: “This has been an incredibly lucky period for players on the island of Ireland.
“In January a Northern Ireland couple won an amazing €127m [£110m] in the EuroMillions jackpot. The luck of the Irish is definitely in the air.”
It was the 14th Irish EuroMillions winning ticket since the game began in Ireland in 2004.
This record breaking win tops the £99 million (€115m) won by Dolores McNamara, from Limerick, in July 2005.
The second biggest win was in 2008 when a player from Tipperary won £13m (€15m) in 2008.
