Boxers Kellie Harrington and Brendan Irvine will carry the Irish flag in the athlete's parade at the opening ceremony of the Tokyo Olympics on Friday.
Former world champion Harrington will be making her debut at the Games while Irvine, a former European and Commonwealth Games medallist, competed in Rio in 2016.
Harrington said: "This means so much to me, to be able to represent not only myself as a person, but as a boxer, for boxing, for my family and for Ireland.
"It's an amazing honour, there are so many athletes out here, and to be chosen as one of the flagbearers is absolutely fantastic."
As part of its commitment to gender equality, the International Olympic Committee involved all competing nations to nominate a male and female athlete to share flag-carrying duties.
