Shrone Austin (born January 31, 1989) is a Seychellois swimmer, who specialized in freestyle and breaststroke events.

[2] Austin made her own swimming history, as Seychelles' youngest ever athlete (aged 15), at the 2004 Summer Olympics in Athens, where she competed in the 100 m breaststroke.

Swimming in heat one, she raced to third and forty-third overall in her lifetime best of 1:19.02, almost a full-second margin behind Armenia's Varduhi Avetisyan (0.15) and three-time Olympian and leader Katerine Moreno (0.67).

[3][4] At the 2008 Summer Olympics in Beijing, Austin decided to drop her breaststroke specialty, and instead challenge herself with a long-distance freestyle.

Swimming against Hungary's Boglárka Kapás, and Thailand's Natthanan Junkrajang (who later forced to pull out from the prelims) in heat one of the 400 m freestyle, Austin came up with a steady swim throughout the race, but could not catch her Hungarian rival near the wall to finish only in second and forty-first at 4:35.86.
