Zap Comix is an underground comix series which was originally part of the youth counterculture of the late 1960s. While a few small-circulation self-published satirical comic books had been printed prior to this, Zap became the model for the "comix" movement that snowballed after its release. The title itself published 17 issues over a period of 46 years.

Underground comix are small press or self-published comic books that are often socially relevant or satirical in nature. They differ from mainstream comics in depicting content forbidden to mainstream publications by the Comics Code Authority, including explicit drug use, sexuality, and violence. They were most popular in the United States in the late 1960s and 1970s, and in the United Kingdom in the 1970s.
