Halil Mutlu (born Halil Aliev (Bulgarian: Халил Алиев)[1] on 14 July 1973 in Postnik, Bulgaria) is a former professional Turkish weightlifter with several World and Olympic championship titles.

Mutlu is one of the six weightlifters who has achieved three consecutive gold medals at the Olympic Games.

His career appeared in doubt after a torn right rotator cuff and ruptured biceps tendon sidelined him for most of 2002.

The Turkish Weightlifting Federation itself had been suspended by the IWF for "repeated anti-doping violations" until May 2006.

He pulled out of the 2008 Beijing Olympics stating that he was not able to "lift my targeted weight in practice."
