The Sandman is an American comic book series written by Neil Gaiman and published by DC Comics imprint Vertigo. Its artists include Sam Kieth, Mike Dringenberg, Jill Thompson, Shawn McManus, Marc Hempel, and Michael Zulli, with lettering by Todd Klein and covers by Dave McKean. Beginning with issue No. 47, it was placed under the Vertigo imprint. It tells the story of Dream of the Endless, who rules over the world of dreams. The original series ran for 75 issues from January 1989 to March 1996, with Gaiman's contract stipulating that the series would end when he left it.

The main character of The Sandman is Dream, also known as Morpheus and other names, who is one of the seven Endless. The other Endless are Destiny, Death, Desire, Despair, Delirium–who was once Delight–and Destruction–who turned his back on his duties. The series is famous for Gaiman's trademark use of anthropomorphic personification of various metaphysical entities, while also blending mythology and history in its horror setting within the DC Universe. The Sandman is a story about stories and how Morpheus, the Lord of Dreams, is captured and subsequently learns that sometimes change is inevitable. The Sandman was Vertigo's flagship title, and is available as a series of ten trade paperbacks, a recolored five-volume Absolute hardcover edition with slipcase, in a black-and-white Annotated edition, and is available for digital download. Critically acclaimed, The Sandman was one of the first few graphic novels ever to be on the New York Times Best Seller list, along with Maus, Watchmen and The Dark Knight Returns. It was one of five graphic novels to make Entertainment Weekly's "100 best reads from 1983 to 2008," ranking at No. 46. Norman Mailer described the series as "a comic strip for intellectuals." The series is noted for having a large influence over the fantasy genre and graphic novel medium since then.
