Jonathan Alan Horton (born December 31, 1985) is a retired American artistic gymnast. He is the 2008 Olympic silver medalist on high bar, the 2010 Worlds all-around bronze medalist, a two-time U.S. National All-Around Champion, and a 17-time medalist at the U.S. National Championships. He was also part of the national team competing at the 2012 Summer Olympics in London, where qualified for the horizontal bar event final and finished in sixth place, but in 2016, he had surgery on his left rotator cuff and as a result was unable to qualify for the 2016 Olympics in Rio de Janeiro.
Horton began gymnastics at the age of four in 1990. "I was a wild child", Horton said, "I once climbed a pole in the middle of Target all the way to the ceiling. I used to do back flips on my parents' bed and I rode a garage door to the top when I was 3 years old."
Horton made his debut as a senior (despite still competing as a junior) in 2002 competing at the U.S. National Championships in Cleveland, Ohio where he placed first on rings and vault, placed second in the all-around and the floor exercise, and tied for fifth on the high bar. In 2003, he competed in the Winter Cup challenge, where he qualified to the individual event finals. Later that year he was chosen to compete for US at the Pan American Games in Santo Domingo where the men's team won bronze and he placed fourth all-around.
