Mettius Fufetius (died in ~670 BC) was a dictator of Alba Longa, an ancient town in central Italy near Rome.

When a full-blown war threatened to erupt between the Albans and the Romans, Fufetius proposed to the third legendary King of Rome, Tullus Hostilius, that a smaller 3 vs. 3 battle (Horatii and Curiatii) should decide the fate of their cities.

Disappointed in the outcome, Fufetius later schemed with Veii, an Etruscan rival of Rome, to provoke a war with his overlord.

Hostilius, after miraculously winning the battle, ruled that since Mettius was torn between the two cities, the same would be done to his body.

His arms were then attached to two chariots that then ran in opposite directions; the result was naturally fatal.
