American SF and fantasy writer, best known for his ''Literature/ChildeCycle[=/=]Dorsai'' future history.

His other works include ''Literature/TheDragonKnight'' series, in which a couple of 20th-century graduate students find themselves in an alternate world that resembles Medieval England but with magic, dragons, and fairies; and the comedy ''Literature/{{Hoka}}'' series, co-written with Creator/PoulAnderson, about a planet whose inhabitants spend all their time pretending to be characters from Earth fiction.
!!Works by Gordon R. Dickson with their own trope pages include:

* ''Literature/ChildeCycle''
* ''Literature/TheDragonKnight'' series
* ''Literature/{{Hoka}}'' series (with Creator/PoulAnderson)

!!Other works by Gordon R. Dickson provide examples of:

* BlueAndOrangeMorality: Dickson loved this trope. If there are humans and aliens in the story, there's definitely ValuesDissonance and misunderstanding, often very deep. [[HumansThroughAlienEyes For both sides.]] It even happens between humans from different planets. How successful, convincing or realistic those systems of values were, is... ''very'' debatable.
** Occasionally subverted, like in ''The Odd Ones'' short story. Aliens ascribe different disgusting ideas to humans, up to and beyond HumanResources, but in the end humans prove quite nice from their point of view, and all visible oddities stem from having two sexes.
* DeflectorShields: In ''Way of the Pilgrim'' the personal force-shield of any Aalag soldier would allow him to hold out indefinitely against any weapons humanity could throw at him. Even nukes. The ship-board version is presumably even more robust.
* {{Heavyworlder}}: ''Hour of the Horde'' and some short stories add an uncommon corollary: on a high-gravity world things fall faster (because of higher acceleration). A HumanoidAlien from such a world is somewhat stronger, but much faster, because falling over on such a planet is a ''bad'' idea and being able to catch falling things is usually helpful too.
* HumansAreSpecial / HumanityIsSuperior: If the setting has humans against aliens, humans always win. Often just because they are oh so awesome. In more reasonable works they win by being [[{{Determinator}} very persistent]].
* LaserBlade: In ''Wolfling'' the preferred weapon of High-Born (haughty, but highly advanced Human Aliens ruling an interstellar empire) are hand-sized "pipes" that project an energy beam, length of which can be varied during fight.
* SuperweaponSurprise: In ''The Alien Way'', an aggressive alien race discovers Earth by analysis of floating space debris and launches a covert surveillance mission as a prelude to invasion. Sadly for the aliens, humans not only know about them, they used the alien mission as a tool to psychologically profile the would-be conquerors and find out all about ''their'' civilization and military capabilities. Then humans sent a message about how they've deceived the aliens, together with images of spaceships ready to strike the alien homeworld and an offer of peace.
* TechnologyUplift: Discussed in ''Wolfling'', where mankind meets an interstellar empire of HumanAliens. Every High-Born (a member of the ruling race) receives enough education to uplift a stone-age planet to the imperial level.
* UrsineAliens: The Dilbians.
* VichyEarth: ''The Way of the Pilgrim'' tells a pretty straightforward interpretation of this trope, with the protagonist, a translator/pet for the occupying Aalaag, organizing a revolution with the power of the indomitable human spirit. They have to, since militarily LaResistance is futile--if he had to, one fully armored Aalaag could defeat every human army in an afternoon.
* WorldOfChaos: The whole theme of his novel ''Time Storm'', in which the eponymous storms can change a locale's time frame by thousands of years or more as they pass.
