Aaron Allston was an American science fiction and fantasy writer. He wrote several novels in the Franchise/StarWarsExpandedUniverse, including a third of ''Literature/LegacyOfTheForce'', a third of ''Literature/FateOfTheJedi'', and about half of the novels in the ''XWingSeries'', as well as tie-ins for ''Franchise/{{Terminator}}'' and several roleplaying game settings. Allston also helped write the manual for the original ''VideoGame/WingCommander'', "Claw Marks," as well as the TabletopGame/DungeonsAndDragons ''Rules Cyclopedia'', which combined the rules of the first four Frank Mentzer BECMI boxed sets for Basic D&D into a single volume. He's also known for extensive work on the ''TabletopGame/{{Champions}}'' role-playing game, including the award-winning supplement "Strike Force," which earned him the allegedly-unwanted epithet "Champions Guru."

Among his own non-tie-in works, possibly the best-known is ''Literature/DocSidhe'', which might be described as "Franchise/DocSavage with Elves".

He died on February 27, 2014 while attending a science fiction convention in Branson, Missouri.

His works with their own trope pages include:

* Literature/DocSidhe series
* Literature/GalateaIn2D
* Literature/FateOfTheJedi
* Literature/LegacyOfTheForce
* XWingSeries
