National Lottery CEO Dermot Griffin said: "This is an incredible win for an Irish EuroMillions player and a record win for the National Lottery.
"We are thrilled. 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.
"The shop that sold the winning ticket will not be revealed for a few days. With such a big win we have procedures to go through, but we will reveal the winning location as soon as we can.
"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."
