DisneyWar is a book that serves as an exposé of Michael Eisner's 20-year tenure as chairman and CEO at The Walt Disney Company by James B. Stewart.

[1] Publishers originally planned on releasing the book on March 7, 2005,[2] only to accelerate the launch date to February 9 after vendor demand, and Disney executives had acknowledged recently acquiring a leaked edition of the manuscript.

In his 2006 afterword, author James B. Stewart acknowledged the last conversation he had with his subject (just before the book's initial launch, over the phone):'Eisner vowed that he’d never speak to me again.'

He finally agreed to step down in March 2005, eventually abdicating executive oversight to Bob Iger, less than a month after DisneyWar debuted.

He referred to Stewart as an "accomplished storyteller who had the luck or foresight to stake out a company filled with colorful executives in a glamorous business—at the moment investors decided they had had enough".
