Doom's Day, also called "Doomsday" is a "holiday" in the Eastern European country of Latveria that commemorates and celebrates the reign of the Fantastic Four's most dangerous archenemy Doctor Doom, and an event in the Marvel Comics universe.

It is an eclectic national holiday that is celebrated whenever the ruler of Latveria, Doctor Victor Von Doom, declares it. Thus, the exact date is variable.

Apparently, the Latverian people across the country enjoy this day despite the fact that Doom has ordered them to.



  • Doom's Day is not related to "Doomsday" (one of the many names for the end of the world).
  • Doom's Day shares similarities with Robotnik Day, an enforced "holiday" celebrating and commemorating the time of Doctor Robotnik's complete conquest of the planet Mobius in a nightmarish alternate reality in which Dr. Robotnik possessed complete omnipotence after absorbing the power of the Chaos Emeralds, thus controlling all of Mobius and subjugated it's people.
  • It was mentioned and said by Victor Von Doom himself in the videogame adaptation of the 2005 movie Fantastic Four.
  • It is the name of the intergalactic serial killer Doomsday from the DC Comics.
