Paul Jennings (born 1943) is an Australian children's author, who primarily writes compilations of short stories featuring {{Twist Ending}}s.

The first and second series of television show ''Series/RoundTheTwist'' were written by Paul Jennings and based on his published short stories; episodes after this point were original stories written by other people.

His work is often quirky in style, often drawing upon weird, spooky and fantastical occurrences, including liberal amounts of gross-out humour and NightmareFuel. For these last reasons especially, {{Moral Guardian}}s have frequently questioned the appropriateness of his work for younger readers. For much the same reasons, these younger readers have often loved it.
!!'''Jennings' work provides examples of:'''

* AmbiguousGender: Star, the horse in ''Spaghetti Pig-Out''.
** And, in earlier prints, Beethoven, the budgie in ''Only Gilt'', and Ohda, the dog in ''Smelly Feat''.
* AnyoneCanDie
* BeCarefulWhatYouWishFor: His favourite Aesop.
* BigBrotherBully: The main character of ''Inside Out''; the brothers of the main characters of ''The Velvet Throne'' and ''Ringing Wet''.
* BodyHorror: The main characters of ''Burp'' and ''Nails'', amongst others.
* BodyToJewel: The main character of ''Tonsil Eye 'Tis'' grows a third eye on his finger that cries tears that grow into garden gnomes. In the end, he starts a business selling them.
* CloningBlues: ''The Copy''.
** AmbiguousCloneEnding: Played With - The Copy has the same memories as the main character, and becomes convinced that he is the original, and that "The Copy" is trying to live ''his'' life. It soon turns out the first part of the story is told [[UnreliableNarrator using the clone's memories]] instead of the original's, and the original boy is ''dead''.
** ExpendableClone
* DownerEnding: Quite a lot.
* HoistByHisOwnPetard: In one story, the {{Jerkass}} narrator is a know-it-all bully who regularly taunts and teases people while scoring high on tests. Over the course of the story, the people who he taunts and teases receive free ice cream from a mysterious ice cream man, and subsequently lose the trait he was teasing them about (e.g. a pimply-faced character's acne disappears overnight). Infuriated that he doesn't get any ice cream, he breaks into the man's truck at night and eats all the ice cream he finds. The final part of the story is riddled with spelling and grammatical errors, as the narrator wonders what happened... and can't work out whether one plus one is "free or for?"
** Also, the Gizmos in the Gizmo series wouldn't have caused so much trouble if the characters had just left them alone in the first place.
** The main character of ''The Strap-Box Flyer'' sells a miracle glue that holds anything together... for four hours, at which point it falls apart. He runs into a man who invented the strap-box flyer, which lets you fly. As they fly towards the clouds, all sense of time lost, the inventor casually reveals the conman's flyer is held together with his glue, and just then it falls apart.
--> "He screamed all the way down."
* HurricaneOfPuns: His joint books with Ted Greenwood and Terry Denton, ''Spooner Or Later'' and ''Freeze A Crowd''.
* {{Jerkass}}: One will always show up in his stories, usually as an antagonist, rarely as a protagonist.
* MagicAIsMagicA: His Twist Endings frequently follow logically from a previously established trait or truth of the work.
* {{Mooning}}: The subject of ''Moonies''.
* NightmareFuel: A list of his stories that ''don't'' have some would be the shorter option.
* OnlyMostlyDead: The main character of ''The Naked Ghost''.
* OurMermaidsAreDifferent: In ''Nails'', mermen are established as having legs, but are covered in scales that resemble fingernails.
* PickyPeopleEater: The Slobberers from the series ''Wicked!''
* ScaryScarecrows: ''Know All'' features a scarecrow come to life due to a circus curse.
* {{Spoonerism}}: The whole point of ''Spooner Or Later''.
* TearJerker: A number, especially ''For Ever'' from ''Uncovered!''. Just you try and keep those last few pages in focus!
* TomatoSurprise and TomatoInTheMirror: A number of his stories, but notably ''The Copy''.
* TongueOnTheFlagpole: The story ''Ice Maiden'' features a boy kissing an ice sculpture and getting stuck.
* UrbanFantasy: Most of his stories.
* VerbalTic: ''Without a Shirt'' is about a boy who can't help adding the titular phrase to everything he says.
* [[WidgetSeries Widget]]: His stories can more or less be considered weird Australian things.
* WipeThatSmileOffYourFace: The last line of ''Santa Claws'' is, "I wish you didn't have such a big mouth."
** FridgeLogic: But the wish before that should have wiped away all the wishes, and killed the granter.
* YouCantFightFate: Looking into the eye of a Seeshell lets you see the future, and everything you see will happen- with a mild dash of SelfFulfillingProphecy.
