''Acinonyx'' was proposed by [[Joshua Brookes]] in 1828.<ref>{{cite book |last1=Brookes |first1=J. |year=1828 |title=A catalogue of the Anatomical and Zoological Museum of Joshua Brookes |location=London |publisher=Richard Taylor |pages=16 |chapter=Section Carnivora |chapter-url=https://archive.org/details/b22475886/page/16}}</ref>

Between the late 18th century and the early 20th century, the following ''Acinonyx'' species and [[subspecies]] were described:<ref name=msw3/>
* [[Cheetah|''Felis jubatus'']] by [[Johann Christian Daniel von Schreber]] in 1777 was based on earlier descriptions by [[Georges-Louis Leclerc, Comte de Buffon|Comte de Buffon]] and [[Thomas Pennant]].<ref>{{cite book |author=Schreber, J.

** [[Acinonyx jubatus hecki|''Acinonyx hecki'']] by [[:de: Max Hilzheimer|Hilzheimer]] in 1913 was a captive cheetah from Senegal in the [[Berlin Zoological Garden]], named in honour of the zoo's director.<ref>{{cite journal |last1=Hilzheimer |first1=M. |year=1913 |title=Über neue Gepparden nebst Bemerkungen über die Nomenklatur dieser Tiere |journal=Sitzungsberichte der Gesellschaft Naturforschender Freunde zu Berlin |issue=5 |pages=283–292 |url=https://archive.org/details/sitzungsberichte1913gese/page/n311}}</ref>
In 1993, ''Acinonyx'' was placed in the [[Monophyly|monophyletic]] subfamily Acinonychinae. [[Molecular phylogenetics|Molecular phylogenetic analysis]] has shown that it is the [[sister group]] of the genus [[Puma (genus)|''Puma'']], and it is now placed within the subfamily [[Felinae]].<ref name=msw3/>

In addition, the following [[fossil]] ''Acinonyx'' species were described:

The "Linxia Cheetah" ([[Acinonyx kurteni|"''A. kurteni''"]]) was initially described by Christiansen and Mazák in 2009 on the basis of a skull from Pliocene strata in China, and touted as the most primitive member of the genus.<ref>{{cite journal |last1=Christiansen |first1=P. |last2=Mazák |first2=J.
