The Men's Hammer Throw event at the 2009 World Championships in Athletics was held at the Olympic Stadium on August 15 and August 17. With reigning champion Ivan Tsikhan banned from competition for doping offences, the 2008 Olympic gold and silver medallists Primož Kozmus and Krisztián Pars were the favourites in the event. Pars entered the competition with a world-leading throw of 81.43 m and an 18 competition win-streak. Belarusian Yuriy Shayunov and Russian Aleksey Zagornyi, the only other athletes to have thrown over eighty metres twice that season prior to the championships, were identified as possible podium finishers. Nicola Vizzoni, Igor Sokolov, Olli-Pekka Karjalainen, Szymon Ziółkowski, Koji Murofushi, and Libor Charfreitag were all predicted to have an outside chance of a medal.
