Walkabout is a 1971 adventure survival film directed by Nicolas Roeg and starring Jenny Agutter, Luc Roeg, and David Gulpilil. Edward Bond wrote the screenplay, which is loosely based on the 1959 novel by James Vance Marshall. It centres on two white schoolchildren who are left to fend for themselves in the Australian Outback and who come across a teenage Aboriginal boy who helps them to survive.

Roeg's second feature film, Walkabout was released internationally by 20th Century Fox, and was one of the first films in the Australian New Wave cinema movement. Alongside Wake in Fright, it was one of two Australian films entered in competition for the Grand Prix du Festival at the 1971 Cannes Film Festival. It was subsequently released in the United States in July 1971, and in Australia in December 1971.

In 2005, the British Film Institute included it in their list of the "50 films you should see by the age of 14".
