Eastern Standard Tribe is a 2004 science fiction novel by Canadian writer Cory Doctorow.

Art has an idea for peer-to-peer music sharing between automobiles, and plans to give it to the EST (taking a cut to himself).

However, his girlfriend meets his coworker, Fede, and they plan to double cross the EST and sell the idea to another tribe.

"[1] Regina Schroeder in reviewing for Booklist said that "Doctorow’s fast, bizarre follow-up to Down and Out in the Magic Kingdom is a reaction to the impact of instant global communication in which it is hard to tell whether the phenomena being reacted to have actually been observed or are the consequences of his imagination.

Cory Doctorow pushes the envelope a bit, because very little of the present story is particularly serious, but the satire is done with so light a touch that it's not intrusive at all."
