Colossus and the Headhunters (Italian: Maciste contro i cacciatori di teste, lit. ‘Maciste against the head-hunters’), is a 1963 Italian peplum film directed by Guido Malatesta.

Maciste arrives on an island only to find it rocked by a catastrophic volcanic eruption…and sinking. The survivors board Maciste’s raft, and he pilots it toward a nearby yet unknown island. The group gets captured by a tribe led by Queen Amoa. Her people are under continuous attack by another tribe on the island—a tribe of savage headhunters. Maciste and his survivors decide to help her, so he and some of his friends set out to find Amoa’s father. They travel to a ruined castle occupied by the headhunters—which used to be a great city of gold—and find Amoa’s father, now blind, imprisoned alone in one of the dungeon rooms by the headhunters. Meanwhile, the leader of the headhunters captures Amoa and decides to marry her by compelling her father to give his blessing. A large battle erupts at Queen Amoa’s village when the headhunters attack. During the fight, the headhunter leader abducts Queen Amoa. Maciste pursues them, saves Amoa, and fights and defeats the wily leader of the headhunters. Having saved the day, Maciste rides away on his raft with Amoa in his arms.

Colossus and the Headhunters was partially shot in Ljubljana in Yugoslavia. For some special effects scenes, Maletesta re-used the volcano footage from his previous film Fire Monsters Against the Son of Hercules. Filming was finished in 1962, which allowed the director to finish working on Fire Monsters Against the Son of Hercules.

Colossus and the Headhunters was released in Italy on 10 January 1963 with an 81-minute running time.
