Team USA's starting Olympics flag bearer lineup is set ... two days after the Americans picked LeBron James to be the male one -- they announced Coco Gauff will be the female one.
The two will hold the Stars and Stripes high and proud at the Games' opening ceremony festivities on Friday in France ... and when the tennis star learned of the honor on Wednesday, she was pumped.
After some initial shock, she told TODAY she had "no words, honestly."
The 20-year-old -- who won her first major at the US Open in 2023 -- now becomes the youngest athlete ever to be named flag bearer.
