Mike Heisler is an American comic book writer and letterer whose career spans more than three decades. He broke into the industry in the late 1980s, establishing himself first as a letterer — primarily through extensive work at Marvel Comics, where credits on titles like Thor helped build his reputation. Over time he transitioned into writing and editing, broadening his footprint considerably.

Among the titles most associated with his name are The Maxx and its later repackaged edition The Maxx: Maxximized, alongside Image and WildStorm properties such as DV8, Cyberforce, and Union. Within the Gen13 universe he wrote both the interactive mini-series Gen13: Interactive and the standalone one-shot Gen13: The Unreal World. His work also extended to Dark Horse Comics, and across a career active from 1989 through at least 2022 he accumulated credits on more than 200 issues.

Beyond periodical comics, Heisler moved into editorial work, and in December 2009 he was announced as editor of a revived Famous Monsters of Filmland, the influential monster-movie magazine that had shaped generations of genre enthusiasts. The appointment signaled both his love of genre storytelling and his versatility as a comics industry professional. No major awards are documented in the available record, but his longevity across lettering, writing, and editing reflects a career built on consistent craft rather than a single defining moment.
