Stacy Westfall (born September 26, 1974) is a professional horse trainer who specializes in reining. She was the first woman to compete in and win the Road to the Horse competition. In 2006 she won the All American Quarter Horse Congress Freestyle Reining competition on the black mare, Whizards Baby Doll, riding both bridleless and bareback. The video of this ride went viral on the internet and brought Westfall to the attention of the non-horse world.
