1910's to 30's Creator/StratemeyerSyndicate kids' series following the adventures of boy inventor Tom Swift. Each book began with Tom inventing some new gadget that conveniently proved essential to resolving the plot. Invented or popularized many GadgeteerGenius tropes.

While popular in his time, Tom proved to have less staying power than his Stratemeyer stablemates [[Literature/TheHardyBoys Frank and Joe Hardy]] and Franchise/NancyDrew, perhaps because of how quickly his "cool technology" was superseded in the real world. An Atomic-age attempt to revive the franchise with a new series starring his son failed when people started questioning the wisdom of atomic-powered airplanes and automobiles. If anything Tom Swift Jr.'s Gee-whiz tech went obsolete even faster than his father's did.

Revived IN SPACE! in the early 1980s, in [[HollywoodCalifornia Southern California]] in the 1990s and [[http://tomswift.bobfinnan.com/ts5.htm in the first person]] in the 2000s.

Origin of the "TomSwifty", such as ''"Pass me the shellfish," said Tom crabbily'' or ''"How was your colonoscopy?" asked Tom probingly.'' This is something of a BeamMeUpScotty (or "Play it again, Sam") situation, as while Stratemeyer was [[http://www.fun-with-words.com/tom_swifties_history.html eager to employ adverbs]] and [[http://en.wikipedia.org/wiki/Tom_Swifty reluctant to use]] [[SaidBookism the plain verb "said"]], actual "Tom Swifty" puns were rare.
* AlternateUniverse: In one of the 90s books, Tom accidentally swaps places with a MadScientist version of himself from one of these due to a black hole experiment gone wrong, with many of friends' analogues being criminals in the alternate universe (and his best friend being a police officer and implied recurring nemesis of his).
* AntiquatedLinguistics: Inevitable, due to the time they were written.
* CharacterNameAndTheNounPhrase: Probably the UrExample.
* {{Deconstruction}}: Intentionally or not, many of the 1990s books did this to "ForScience" as a motivation for Tom's various inventions. Many of them prove to cause all manner of unforeseen problems for Tom and his friends to deal with. Tom can come off as a younger more idealistic version of a MadScientist.
* EitherOrTitle: All of the books in the original series, such as ''Tom Swift and His Motor Cycle; or, Fun and Adventure on the Road''
* ForScience: Because what else would a supergenius teenager get up to in a series of adventure novels?
* FirstContactMath: Tom Swift Jr. and his father communicate with aliens this way.
* GadgeteerGenius: Possibly the UrExample of this trope too.
* KidDetective
* LukeIAmYourFather: In the nineties series, [[BigBad The Black Dragon]] attempts to recruit Tom, claiming that Tom is actually his son, from a past relationship between the villain and Tom's mother. After rolling the idea around in his head for a short bit, Tom decides he [[GenerationXerox takes entirely too much after Tom Sr.]] for the Black Dragon's claims to be anything but an attempt to mess with his head.
* MadLibsCatchPhrase: Mr. Damon in the first series always said some form of "Bless my [noun]!"
* MinovskyPhysics: The radiation-blocking Tomasite plastic can block radiation, and is a good neutron reflector. Period. Apart from that, it's just a strong, hard plastic. The repelatron device can do one thing: Push on the specific combination of elements it's been tuned to. The potential complications and the difficulties of keeping the things properly tuned are not ignored.
* {{MST}}: ''[[http://keithpalmer.ca/mst3k/favourites/tom-swifts-war-tank.txt Tom Swift's War Tank]]'' is one of the more extensive {{MSTing}}s available. It has its own tropes page, [[FanFic/TomSwiftAndHisWarTank here]].
* ParrotExposition: Notoriously overused in the earlier novels and the source for much of the humor in the aforementioned {{MSTing}}.
* RaygunGothic including the inevitable {{Zeerust}}
* RealityEnsues: Particularly in the 90s series.
** Invoked in ''Aquatech Warriors'', in which the BigBad plans to use a massive conventional bomb to raise an island into the sea he can call his own. After his plan is thwarted, Tom tells the gang what would have happened if the plan had succeeded: No new island nation for the BigBad; "only" a tsunami that would have hit Jamaica, killing upwards of 50,000 people.
** In ''Death Quake'', being only eighteen, Tom has a difficult time being taken seriously by a visiting adult scientist.
** In Quantum Force: Tom Swift uses his newest invention to exact some payback on some muggers -- and gets grounded as soon as he gets home for doing something so stupid.
* {{Revival}}: Tom Swift Jr. in the 1950s, and again in the 1980s, and again in the 90s, and for good measure in 2006.
* [[RecycledINSPACE Recycled IN SPACE!]]: The adventures of Tom Swift the Somethingth, interstellar traveller.
* SaidBookism
* {{Sidekick}}: Mr. Damon and Ned in the original series, Bud in the 1950s, Ben in the 1980s, Rick in the 1990s. Given who they're playing the Sidekick to, they also get to be TheWatson.
* StoryArc: The "Jr." novels had an ongoing arc about Tom's interaction with the alien "Space Friends". Since the arc never really went anywhere before the series ended, it's arguably also an AbortedArc.
* TeenGenius: Tom, of course, and his twin sister as well in the 90's version. Tom is probably the UrExample of this trope as well.
* TomSwifty: TropeNamer, though as mentioned actual examples are rare.
