Katie Taylor will begin life as a professional fighter with a Wembley Arena bout next month - before fighting on the undercard of Anthony Joshua's IBF world heavyweight title defence in December.
Eddie Hearn's Matchroom Boxing team confirmed today that they've agreed terms with Bray woman, who will make her pro debut live on Sky Sports on 26 November.
Despite a disappointing Rio Games that saw the 30-year-old beaten by Finland's Mira Potkonen in the quarter-finals, Taylor has largely dominated the amateur game, collecting five world titles, six European crowns and an Olympic gold in an astonishing career. She's now ready for a fresh challenge.
I'm excited for the road ahead - Katie Taylor
“When I first dreamt of Olympic gold, female boxing was practically unknown,” she said.
“Now because of my journey and the incredible supporters who came along with me, female boxing is as much part of the fabric of the Olympics as its male counterpart.
"I want to do the same for the professional sport and I hope those who have supported me along the way will come along with me. I'm excited for the road ahead.”
Taylor's road to the world title she craves begins in London in four weeks' time before a second pro outing at the Manchester Arena on 10 December on the Joshua undercard.
“Today marks a significant day for our sport with the news that Katie is joining the professional ranks,” said promoter Hearn.
“She is one of the most decorated amateur boxers of all time and a public icon in Ireland.
"I met Katie for the first time last week and was fascinated by her desire to not just win world titles but to break down the barriers of women's boxing, she is an incredible role model.
“Boxing is a sport open to all but it's also an entertainment business. Anyone who has watched Katie fight knows how exciting she is.
"I'm really excited by this challenge and we are committed to giving Katie the opportunities she needs to achieve her dreams.”
