Jessica Cosby is an American hammer thrower. She competed at the 2007 World Championships and the 2008 Olympic Games without reaching the final. Her personal best throw is 72.21 metres, achieved on August 20, 2009 in Berlin, Germany, which brought her seventh place at the 2009 World Championships. Shortly after the 2009 Championships, she failed a random, out-of-competition drug test. She explained that the banned diuretic had entered her system as a result of taking a water pill to aid urination. Cosby said that depression, brought on by a series of personal and sporting setbacks, had left her unable to pass water and that her mother had given her the pill. Following an arbitration meeting with the US Anti-Doping Agency, the panel accepted her version of events and she received a reduced ban of four months. Cosby was runner-up at the 2010 USA Outdoor Championship, but won the national title in the hammer the following year. She reached the final at the 2011 World Championships in Athletics and placed eleventh overall. She set a new personal record at the 2012 Prefontaine Classic, throwing the implement 74.19 m for fourth place.
