The Daily Planet is a fictional newspaper appearing in American comic books published by DC Comics, commonly in association with Superman. The newspaper was first mentioned in Action Comics #9 (November 13, 1939) – Underworld Politics, War on Crime. The Daily Planet building's distinguishing feature is the enormous globe that sits on top of the building.

Based in the fictional city of Metropolis, the paper employs Clark Kent, Lois Lane, Jimmy Olsen, and Perry White as its editor-in-chief. The building's original features were inspired by the Old Toronto Star Building where Superman's co-creator, Joe Shuster, was a newsboy when the Toronto Star was still called the Daily Star. Shuster has claimed that Metropolis was visually inspired by Toronto. Over the years, however, Metropolis has come to serve as an analogue to New York City.

When Superman first appeared in comics (specifically 1938's Action Comics #1), his alter ego Clark Kent worked for a newspaper named the Daily Star, under editor George Taylor. Joe Shuster named the Daily Star after the Toronto Daily Star newspaper in Toronto, Ontario, which had been the newspaper that Shuster's parents received and for which Shuster had worked as a newsboy. It was not until later that the fictional paper became the Daily Planet. (The real-world newspaper was called the Evening Star prior to 1899; the Toronto Daily Star is now known as the Toronto Star.)

While choosing a name for the fictitious newspaper, consideration was given to combining the names of The Globe and Mail (another Toronto newspaper) and the Daily Star to become The Daily Globe. But when the comic strip appeared, the newspaper's name was permanently made the Daily Planet to avoid a name conflict with real newspapers. In Superman #5 (Summer 1940), the publisher of the Daily Planet is shown to be Burt Mason, a man who is determined to print the truth even when corrupt politician Alex Evell threatens him. In Superman #6 (September–October 1940), Mason gives free printing equipment to The Gateston Gazette after its editor, Jim Tirrell, is killed and its equipment is destroyed by racketeers that Tirrell insisted on reporting.

When DC made use of its multiverse means of continuity tracking between the early 1960s and mid-1980s, it was declared that the Daily Star was the newspaper's name in the Golden Age or "Earth-Two" versions of Clark Kent, Lois Lane and Jimmy Olsen, while the Daily Planet was used in the Silver Age or "Earth-One" versions. The Clark Kent of Earth-Two eventually became the editor-in-chief of the Daily Star, something his Earth-One counterpart did not achieve.

In the Silver and Bronze Age universes, Clark's first contact with the Daily Planet came when reporter (and future editor) Perry White came to Smallville to write a story about Superboy, and wound up getting an interview where the Boy of Steel first revealed his extraterrestrial origins. The story resulted in Perry earning a Pulitzer Prize. During Clark Kent's years in college, Perry White was promoted to editor-in-chief upon the retirement of the Daily Planet's previous editor, the Earth-One version of George Taylor.

After graduating from Metropolis University with a degree in journalism, Clark Kent went to work at the Planet, and quickly met Lois Lane (who had been working there for some time already). After Clark was hired, Jimmy Olsen joined the paper's staff.

In 1971, the Daily Planet was purchased by Morgan Edge, president of the Galaxy Broadcasting System. Edge proceeded to integrate Metropolis television station WGBS-TV's studios into the Daily Planet building, and named Clark Kent as the anchor for the WGBS evening news. Lana Lang, Clark's former schoolmate from Smallville, joins him as a co-anchor.
