The League of Extraordinary Gentlemen: Black Dossier is an original graphic novel in the comic book series The League of Extraordinary Gentlemen, written by Alan Moore and illustrated by Kevin O'Neill. It was the last volume of the series to be published by DC Comics. Although the third book to be published, it was not intended to be the third volume in the series. Moore has stated that it was intended to be "a sort of ingenious sourcebook", and not a regular volume.

Black Dossier was released on November 14, 2007.

Originally referred to as The Dark Dossier during early announcements of its existence, The League of Extraordinary Gentlemen: Black Dossier differs from the other regular volumes, as it is a self-contained graphic novel designed to be a "sourcebook" for the series. While the first two volumes included prose stories as backup features, the majority of Black Dossier consists of non-comic pieces, taking the form of prose stories, letters, maps, guidebooks, magazines and even a lost Shakespeare folio. Also included is a 'Tijuana Bible' insert and a 3-D section complete with custom glasses. However, these prose pieces and inserts are framed by a comic story, in which Mina Harker and Allan Quatermain obtain the Black Dossier itself and are then pursued by government forces.

All illustrations are done by Kevin O'Neill, the artist on the first two volumes. Alan Moore also recorded a vinyl record of him singing an original song that would be released with the book, but DC did not include it.

After many changed shipping dates, the Absolute Edition was released with no vinyl record, no script/sketch companion book (something that had shipped with Absolute "League" volumes 1 & 2), and a price point of $99 – $24 higher than the two previous Absolute "League" volumes.

Bill Oakley died halfway through designing the book, so the last half was designed by Todd Klein. The book is dedicated to Oakley's memory.
