Karl Ruprecht Krönen is a fictional supervillain in the Hellboy comic book series, created by Mike Mignola.

In the comics, Krönen was a relatively unremarkable Nazi SS scientist, whose most distinguishing characteristic was that he always wore a gas mask and protective bodysuit, which Mignola attributes to a disfiguring accident of some kind.

Director Guillermo del Toro created a significantly expanded biography for the character, to appear as a supervillain in the 2004 film adaptation.
