The Quibbler is a fictional magazine featured in Harry Potter and the Order of the Phoenix.

The magazine's editor is an unusual wizard named Lovegood. Lovegood is aganist the Ministry of Magic's propaganda and the commercialized nature of the Daily Prophet. He is focused on principle rather than on profit. However, he is so open-minded that some of the stories are not only untrue, but incredibly silly, such as Sirius Black being a singing sensation or someone flying to the moon on a broomstick and bringing back a carton of "moon frogs" as proof. It has gone so far that hardly anyone believes any article in The Quibbler, except Lovegood's own daughter Luna. The writers for The Quibbler aren't paid; they do it for the honour.

During Harry Potter and the Order of the Phoenix, Hermione Granger convinces Rita Skeeter to write an article about Harry Potter's meeting with Voldemort that occurred in Harry Potter and the Goblet of Fire. Lovegood agreed to publish this interview in his magazine. Dolores Umbridge, when she discovered this, banned The Quibbler from Hogwarts, in an attempt to prevent the story spreading. Her plan backfired, and no edition of The Quibbler ever sold out faster. Lovegood was shocked that people were more interested in this than the Crumple-Horned Snorkack. After Cornelius Fudge admitted that Voldemort had returned, Lovegood sold the Daily Prophet Harry's interview for a very good price, enough for him and his daughter to go on an expedition to Sweden where they hope to catch a Crumple-Horned Snorkack.

Facts according to The Quibbler

The Ministry of Magic

Lovegood is against the Fudge Administration, and says he'd believe anything of him. This shows in The Quibbler, which declares that Fudge has goblins cooked in pies, uses the Department of Mysteries to develop terrible poisons and has a secret army of fire-demons called "heliopaths". No known characters, except Luna, actually believe all this. Harry said (or rather thought) that although he thought Fudge had some faults, he found it hard to believe him ordering goblins to be cooked in pies.

Fantastic Beasts

There have been numerous beasts mentioned in The Quibbler such as Crumple-Horned Snorkacks, which supposedly live in Sweden and cannot fly, heliopaths, the Bibbering Humdinger and Nargles, which are supposed to infest mistletoe. None of these exist according to Hermione Granger and are not listed in Fantastic Beasts and Where to Find Them, so it's clear that the Ministry of Magic also doesn't recognize their existence.
