Interweb is a slang term referring to the Internet, sometimes more specifically referring to the World Wide Web. The spelling Interweb is usually used with sarcasm or derision, chiding the "uneducated masses" who now frequent the Internet, threatening the once elite hacker culture that was prevalent in the early 1990s. It can also be used to make fun of said "elite hackers".

The first recorded use in this sense was in the Camp Chaos Flash video Metallicops (June 7, 2000. "Interweb Baaaad") an episode in the Napster Bad series mocking Metallica and their campaign against illegal file sharing. Earlier uses in science fiction of the term include the Babylon 5 episodes "Eyes" (1994) and "Passing Through Gethsemane" (1995).

It is a much used term at the Something Awful website, both on the pages themselves and on the forums.

The comedy group Three Dead Trolls in a Baggie also used the phrase in their skit "Keep your parents off the internet". The anti-hero of the story is trying to persuade his computer illiterate father not to go online, and he responds with "Your old man is going to be on the interweb!".

On A&E at 20:32 CST on Friday, November 26, 2004, a commercial for HP was witnessed where the phrase "Are we on the interweb?" was used.
