!!Works by Margaret Mahy with their own trope pages include:

* ''Literature/TheChangeover''

!!Other works by Margaret Mahy provide examples of:

* AfterTheEnd: ''Maddigan's Fantasia'' is set some time 'after the Great Chaos changed the shape of the world'. The Chaos itself is never described or hinted at, but the entire series is spent trying to ensure that the existing state of things doesn't get any worse.
* AlienAmongUs: ''Aliens in the Family''
* CircusBrat: The protagonist of ''Maddigan's Fantasia'', Garland, is the daughter of the circus' Ringmaster.
* EvilIsDeathlyCold: "The Devil and the Corner Grocer" (in ''The Chewing-Gum Rescue and Other Stories'') has the grocer feel a chill whenever the villain walks into the shop. [[spoiler:At the climax, the demon manifests without his disguise, and it's ''freezing'' -- until the grocer calls on the angel who's also been appearing throughout the story, who turns up with a much more convivial temperature.]]
* HellishPupils: The HotWitch in ''Alchemy'' has eyes that initially appear normal, but turn yellow and catlike when examined closely. Somewhat surprisingly, she's a good guy--the antagonist is even creepier.
* HotLibrarian: PlayedForLaughs with Miss Laburnum from ''The Librarian and the Robbers''.
* IJustWriteTheThing: The entire point of "A Villain's Night Out."
* {{Pirate}}: ''The Great Piratical Rambustification'', ''The Pirates' Mixed-Up Voyage''
