Mike Mignola (born in Berkeley, California on September 16, 1960) is a American comic book artist and writer. He has also worked for animation projects such as Atlantis: The Lost Empire and the adaptation of his one shot comic book, The Amazing Screw-On Head.

Mignola is particularly noted for his highly distinctive style, which was once called "German expressionism meets Jack Kirby" by Alan Moore, in an introduction to a collection of Mignola's Hellboy works.

While Mignola has heavily influenced a new generation of comics artists since he began working on Hellboy, he was something of an odd man out in the superhero comics industry in the beginning of his career. Mignola's imagery stood in stark contrast to the style of his contemporaries. Where others would draw muscular men and slim, well-endowed women, Mignola's characters were usually bulky and rough-looking, and more often than not defined by large shadowed areas rather than fine details. Mignola often takes the same approach to architecture, particularly in Hellboy, where he often sets the scenes in slowly dilapidating Victorian and Gothic surroundings. He also commonly draws machines that feature steampunk imagery.
