Tank Girl is a British comic character created by Alan Martin and Jamie Hewlett. It first appeared in print in 1988 in the British comics magazine Deadline, and then in the solo comic book series Tank Girl. After a period of intense popularity in the late 1980s and early 1990s, Tank Girl inspired a 1995 feature film. After a long hiatus, the character returned to comics in 2007 and has appeared regularly in the years since.

Originally written by Martin and drawn by Hewlett, the character has also been drawn by Philip Bond, Glyn Dillon, Ashley Wood, Warwick Johnson-Cadwell, Jim Mahfood, Brett Parson, Jonathan Edwards, Craig Knowles, Rufus Dayglo, Andy Pritchett, and Mike McMahon.

Tank Girl (Rebecca Buck – later revealed to have been born as Fonzie Rebecca Buckler) drives a tank, which is also her home. She undertakes a series of missions for a nebulous organization before making a serious mistake and being declared an outlaw for her sexual inclinations and her substance abuse. The comic centres on her misadventures with her boyfriend, Booga, a mutant kangaroo. The comic's irreverent style is heavily influenced by punk visual art, and strips are frequently deeply disorganized, anarchic, absurdist, and psychedelic. The strip features various elements with origins in surrealist techniques, fanzines, collage, cut-up technique, stream of consciousness, and metafiction, with very little regard or interest for conventional plot or committed narrative.

The strip was initially set in a post-apocalyptic (rendered self-fending due to an implied nuclear armageddon) Australia, although it drew heavily from contemporary British pop culture.

Martin and Hewlett first met in the mid-1980s in Worthing, while studying at The West Sussex College of Art and Design (WSCD, later renamed Northbrook College). Martin was in the college band The University Smalls with fellow comics enthusiast Philip Bond. One of their songs was called "Rocket Girl". They had started adding the suffix 'girl' to everything habitually after the release of the Supergirl movie, but "Rocket Girl" was a student at college on whom Bond had a crush and who apparently bore a striking resemblance the Love and Rockets character Hopey. Martin and Hewlett began collaborating on a comic/fanzine called Atomtan, and while working on this, Hewlett had drawn:

A grotty-looking beefer of a girl brandishing an unfeasible firearm. One of our friends was working on a project to design a pair of headphones and was basing his design on the type used by World War II tank drivers. His studio in Worthing was littered with loads of photocopies of combat vehicles. I pinched one of the images and gave it to Jamie who then stuck it behind his grotty girl illustration and then added a logo which read 'Tank Girl'.

The image was published in the fanzine as a one-page ad, but the Tank Girl series first appeared in the debut issue of Deadline (1988), a UK magazine intended as a forum for new comic talent, and it continued until the end of the magazine in 1995.

Tank Girl became quite popular in the politicized indie counterculture zeitgeist as a cartoon mirror of the growing empowerment of women in punk rock culture. Posters, shirts, and underpants began springing up everywhere, including one especially made for the Clause 28 march against Margaret Thatcher's legislation. Clause 28 stated that a local authority "shall not intentionally promote homosexuality or publish material with the intention of promoting homosexuality" or "promote the teaching in any maintained school of the acceptability of homosexuality as a pretended family relationship." Deadline publisher Tom Astor said, "In London, there are even weekly lesbian gatherings called 'Tank Girl nights.'"
