2013 IAAF Hammer Throw Challenge

The 2013 IAAF Hammer Throw Challenge was the fourth edition of the annual, global series of hammer throw competitions organised by the International Association of Athletics Federations. The winners were Paweł Fajdek (244.23 metres) and Anita Włodarczyk (233.83 metres), both of Poland. Both the final scores were records for the challenge.

A total of fifteen meetings featured on the circuit, with nine women's and nine men's contests spread across those events. The point scoring format was cumulative – the final standings were decided by the sum of athletes' three best throws on the circuit. Only the best throw by an athlete from each meet was taken into consideration.
