Mark Beyer (born October 8, 1950) is a self-taught American artist and former cartoonist. His comics were known for their bleak story lines, often featuring death, disfigurement, depression, and humiliation, which contrasted with his self-taught, geometric drawing style. Most of his stories were about the adventures of a codependent yet resentful couple named Amy and Jordan. Beyer made one final comic strip for the summer 2012 issue of the British magazine ArtReview.

Beyer is originally from Allentown, Pennsylvania in the Lehigh Valley region of eastern Pennsylvania. He is a self-taught, outsider artist whose work has appeared in Raw Vision magazine.

Beyer's work was prominently featured in all but two issues (#3 and 4) of Raw magazine. He has also been published in New York Press and New Musical Express. Beyer also had a recurring animated short series on MTV's Liquid Television (The Adventures of Thomas and Nardo); and a 1995 movie by Gregg Araki, The Doom Generation, was loosely based on the Amy and Jordan strips.

He has also produced cover artwork, including Xman and *** by Michael Brodsky, T-shirts and posters for John Zorn and the New York Downtown avant-garde music scene. In particular the cover and inserts for Zorn's tribute to Ornette Coleman Spy vs Spy (1989) and a popular Naked City T-shirt.

Although he mostly works solo, Beyer has collaborated with writer Alan Moore.
