The bumper win follows an Irish EuroMillions success earlier this week. The €175 million ticket was sold in Naul village on Tuesday.
There was no winner of the Lotto Plus 1 or Lotto Plus 2 top prizes.
A National Lottery spokesman said it hopes to reveal the name of the winning store in the next couple of days.
National Lottery chief executive Dermot Griffin said the jackpot has been rolling since before Christmas.
“This has been an extraordinary week,” he said.
“We had our highest ever jackpot prize win with a family syndicate winning an incredible €175 million on EuroMillions. Now, just days later, we have a lucky Lotto player who has won this amazing €10.2 million prize.”
