Baron Kriminel is a much feared spirit or Lwa in the Haitian Vodou religion. He is envisioned as a murderer who has been condemned to death, and is invoked to pronounce swift judgment.

When a person becomes possessed by Baron Kriminel they shout obscenities, spit and try to stab surrounding people. If, during possession, Baron Kriminel is presented with food he does not like, he will bite chunks out of the arms of the possessed person. He sometimes calls for sacrifices of black chickens to be doused in petrol and set alight. The shrieking of the chickens when being burned alive is said to appeal to the cruel nature of Baron Kriminel and appease him.

Baron Kriminel is often represented by Saint Martin de Porres. His colours include black, purple, white and deep blood red.

Baron Kriminel will often grant requests in lieu, he is said to return on Fete Ghede, or the Voduns' Day of the Dead, to claim payment.
