Here Comes Everybody: The Power of Organizing Without Organizations is a book by Clay Shirky published by Penguin Press in 2008 on the effect of the Internet on modern group dynamics and organization. The author considers examples such as Wikipedia, MySpace, and other social media in his analysis. According to Shirky, the book is about "what happens when people are given the tools to do things together, without needing traditional organizational structures". The title of the work alludes to HCE, a recurring and central figure in James Joyce's Finnegans Wake and considers the impacts of self-organizing movements on culture, politics, and business.

Clay Shirky is an American writer, consultant and teacher on the social and economic effects of Internet technologies and journalism.
