Michelle Smith offered her congratulations to Irish gold medalists Fintan McCarthy and Paul O'Donovan, while defending her 1996 wins.
The two rowers from Cork took the gold in the men's lightweight double sculls, making them the seventh gold medal-winning athletes in Irish history.
Michelle Smith de Bruin is now a barrister, but won three gold medals and one bronze at the Atlanta Olympics in 1996.
In 1998, she was banned for four years for tampering with a urine sample, though she never failed a drug test and was not stripped of her medals.
RTÉ's Liveline reached out to the Olympian after it was noted by a listener that RTÉ presenters failed to mention Smith de Bruin when discussing past gold medalists during their Tokyo coverage last night.
Smith de Bruin sent her congratulations to the two rowers, and described how proud she was winning her medals and the memories people have of her wins in those games.
She wrote:
"I just want to congratulate our brilliant rowers, Fintan McCarthy and Paul O'Donovan, on their wonderful achievement in becoming Ireland's newest Olympic Champions. What a stunning performance.
"Twenty-five years ago this week, I became the first Irish woman to win an Olympic Gold medal.
"By the end of that week in Atlanta, I had become a Triple Olympic Champion. It was the culmination of seventeen years training and dedication to my sport.
"Standing on the podium, watching the tricolour being raised and listening to Amhran na bhFiann was and still is, the proudest moment of my life.
"Twenty-five years have passed and people still stop to tell me where they were when I won my medals. I will always be incredibly proud of what I achieved in Atlanta and remain touched by the level of support still shown to me by the people of Ireland.
"Michelle Smith de Bruin.
"Triple Olympic Champion, 1996."
The statement was sent to LiveLine in response to an email from a listener that said: "I am following the RTE coverage of the Olympics and so far Michelle Smith has not been mentioned once. She is our greatest Olympian and I am ashamed at how she is being treated by RTE."
