''Cosmic Fantasy'' was the flagship RolePlayingGame franchise from Creator/TelenetJapan's Laser Soft division, created exclusively for the [[TurboGrafx16 PC-Engine]]'s CD attachment, with one CompilationRerelease for the UsefulNotes/SegaCD and masterminded by manga artist KazuhiroOchi.

Like Sega's own RPG franchise ''VideoGame/PhantasyStar'', ''Cosmic Fantasy'' combined anime presentation with a [[ScienceFantasy mixture of fantasy and sci-fi]]. However, by utilizing the CD format, ''CF'' was among the first such games to rely on fully animated and voice-acted cutscenes not unlike Nihon Falcom's popular ''VideoGame/{{Ys}}'' games or Game Arts' ''Franchise/{{Lunar}}'' games.

It's also fairly notorious for being one strong case of NoExportForYou -- only [[SequelFirst the second game]] ever saw a release outside Japan, thanks to Working Designs.

Games in this series include:

# ''Cosmic Fantasy: Bōken Shōnen Yū'' (1990)
# ''Cosmic Fantasy 2'' (1991)
# ''Cosmic Fantasy 3: Bōken Shōnen Rei'' (1992)
# ''Cosmic Fantasy Stories'' (1992) (the only non-Turbo release; remake of the first two games for the UsefulNotes/SegaCD)
# ''Cosmic Fantasy 4: Ginga Shōnen Densetsu - Totsunyū-hen'' (1994)
# ''Cosmic Fantasy 4: Ginga Shōnen Densetsu - Gekitō-hen'' (1994)

* AllInARow
* AnimalMecha: Marley, a robotic cat.
* TheAnimeOfTheGame
* CatFolk: Very common through the franchise
* CoolMask: Galam.

* GettingCrapPastTheRadar: While ''2'' was still fairly censored in its localization, not all of it was, notably Babbette's ShowerScene.
* OneGameForThePriceOfTwo: The fourth game splits the adventure between the protagonists of 1 and 2.
* RescueThePrincess: Van for Laura.
* ScienceFantasy
* SpacePirates: Or '''Cosmic''' Pirates, rather.
* TakeOverTheWorld: Galam's plan.
* UnfortunateName: Van, and did they really need to use the ''long'' A sound for Galam's first syllable?
* UpdatedRerelease: ''Stories'' is such for the first two games.
