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 Art Review.
He is primarily known as a self-taught outsider artist.
