John Henry Days is a 2001 novel by American author Colson Whitehead.

Building the railways that made America, John Henry died with a hammer in his hand moments after competing against a steam drill in a battle of endurance.

Over a century later, freelance journalist J. Sutter is sent to West Virginia to cover the launch of a new postage stamp at the first John Henry Days festival.

"[1] Writing in The New York Times, novelist Jonathan Franzen likened the novel to Ulysses and Moby-Dick in its "encyclopedic aspirations", but added: "John Henry Days is funny and wise and sumptuously written, but it's only rarely a page turner.
