The 2015 IAAF Hammer Throw Challenge was the sixth edition of the annual, global series of hammer throw competitions organised by the International Association of Athletics Federations. The winners were Paweł Fajdek (248.01 metres) and Anita Włodarczyk (235.28 metres), both of Poland. This was Włodarczyk's third straight title and Fajdek's second title, after his win in 2013. Fajdek and Włodarczyk each improved the challenge record totals. Włodarczyk twice broke the hammer throw world record that year, but these marks were achieved outside of the series.
