Lloyd Llewellyn (sometimes abbreviated LLLL) is a comic book by Daniel Clowes.

The black-and-white series, published by Fantagraphics Books, ran for six issues from April 1986 to June 1987.

- In Love and Rockets #13 which contains the Story "The Last Time I sqaw Irving" and a special preview page (Last Quarter 1985) - in Doosmday Squad #2 (reprinting Charlton's Doomsday+1 #2 by Joe Gil and John Byrne) we find the Story "Under the Big Top" (Early 1986) The series' title character is a detective who has humorous adventures inspired by film noir and stereotypical 1950s lounge culture.

The story "The Nightmare" from Lloyd Llewellyn #6 foreshadowed the approach of Clowes's next comic, Eightball, by breaking the conventions of the series' crime setting and turning to social satire.

Also in that issue, the author announces: ... And who knows ... somewhere along that lonesome road we might see a new LLLL mag with a brand new format so dazzling, so breathtaking, so monumentally fantastic that I haven't even thought of it yet!Early issues of Eightball included several additional Lloyd Llewellyn episodes.
