A British comic is a periodical published in the United Kingdom that contains comic strips. It is generally referred to as a comic or a comic magazine, and historically as a comic paper. As of 2014, the three longest-running comics of all time were all British.

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.
