Is Shakespeare Dead?

Is Shakespeare Dead? is a short, semi-autobiographical work by American humorist Mark Twain. It explores the controversy over the authorship of the Shakespearean literary canon via satire, anecdote, and extensive quotation of contemporary authors on the subject.

The original publication spans only 150 pages, and the formatting leaves roughly half of each page blank. The spine is thread bound. It was published in April 1909 by Harper & Brothers, twelve months before Mark Twain's death.

The book attracted controversy for incorporating a chapter from The Shakespeare Problem Restated by George Greenwood without permission or proper credit, an oversight Twain blamed on the accidental omission of a footnote by the printer.
