Ellen Keane says "some dreams do come true" after winning gold at the Paralympics.
She's claimed Ireland's first medal in Tokyo in the SB8 100 metres breaststroke.
President Michael D Higgins has congratulated Ellen on her "outstanding achievement" and says she's an "inspirational athlete".
The Dubliner smashed her previous personal best by almost two seconds in Tokyo.
A bronze medallist in Rio five years ago, the 26-year-old held off the challenge of New Zealand's Sophie Pascoe.
She qualified in first place from the heats in a time of 1 minute 21 point 7-1 seconds.
