The League of Extraordinary Gentlemen is a comic book series by Alan Moore and Kevin O'Neill published by the America's Best Comics imprint of DC comics. The first mini series was six issues in length and has been collected into a single volume. A second miniseries began publication in 2002.

The title is a play upon that of The League of Gentlemen.

The story takes place in 1898 in a fictional world where all of the characters and events from Victorian era literature actually existed. Thus, the world the characters inhabit is one far more technologically advanced than our own was in the same year (see steampunk).

The League is assembled by the British government to protect the empire from various menaces including the criminal genius Professor Moriarty and the Martians from H.G. Wells' novel War of the Worlds.

The individual members of the League include:

• Mina Murray of Bram Stoker's novel Dracula
• Allan Quatermain, the hero of H. Rider Haggard's King Solomon's Mines and its various sequels and prequels
• Captain Nemo from Jules Verne's novels 20,000 Leagues Under the Sea and The Mysterious Island
• Dr. Henry Jekyll and Mr. Edward Hyde, created by Robert Louis Stevenson
• Dr. Hawley Griffin, the Invisible Man from the 1897 novel by H.G. Wells (Mr Moore gave Dr. Griffin his first name, that of legendary murdered Dr Crippin

A film starring Sean Connery and being directed by Stephen Norrington is scheduled for release in July 2003. It reportedly adds additional characters, Tom Sawyer (from the novel by Mark Twain) and Dorian Gray (from the novel by Oscar Wilde).

League's juxtaposition of characters from different sources in the same story is similar to science fiction writer Philip Jose Farmer's works centering around the Wold Newton family.
