Chen is far and away the smallest athlete on our list, coming in at just 4' 6".
The pint-sized Chinese phenom has racked up the medals over the past three years and is now one of the world's elite divers.
At the 2008 Beijing Olympics, Chen gave the home crowd plenty to cheer about. She took gold in 10-meter platform diving and, along with partner Wang Xin, added gold in 10-meter synchronized platform.
She and Wang recently won gold in synchronized at the 2009 World Championships, their second straight world title in that event. Chen also won silver in individual 10-meter platform at the 2009 and '07 World Championships.
At age 17, there's no doubt we'll be seeing big things from this small star over the coming years.
