Krazy Kat is an American newspaper comic strip, created by cartoonist George Herriman, which ran from 1913 to 1944. It first appeared in the New York Evening Journal, whose owner, William Randolph Hearst, was a major booster for the strip throughout its run. The characters had been introduced previously in a side strip with Herriman's earlier creation, The Dingbat Family, after earlier appearances in the Herriman comic strip Baron Bean. The phrase "Krazy Kat" originated there, said by the mouse by way of describing the cat. Set in a dreamlike portrayal of Herriman's vacation home of Coconino County, Arizona, Krazy Kat's mixture of offbeat surrealism, innocent playfulness and poetic, idiosyncratic language has made it a favorite of comics aficionados and art critics for more than 80 years.

A comic strip is a sequence of cartoons, arranged in interrelated panels to display brief humor or form a narrative, often serialized, with text in balloons and captions. Traditionally, throughout the 20th and into the 21st century, these have been published in newspapers and magazines, with daily horizontal strips printed in black-and-white in newspapers, while Sunday papers offered longer sequences in special color comics sections. With the advent of the internet, online comic strips began to appear as webcomics.
