'''Simons's spiny rat''' ('''''Proechimys simonsi''''') is a spiny rat species<ref>{{MSW3 Hystricognathi | id = 13400515 | page = | heading = Species ''Proechimys simonsi''}}</ref> found in Bolivia, Brazil, Colombia, Ecuador and Peru. It was named for American scientific collector Perry O. Simons.<ref>{{cite journal|doi=10.1080/00222930008678378|title=XXXVII.—Descriptions of new Rodents from Western South America|journal=Annals and Magazine of Natural History|volume=6|issue=33|pages=294–302|year=1900|last1=Thomas|first1=Oldfield|url=https://zenodo.org/record/2188735}}</ref>

==Phylogeny== Morphological characters and mitochondrial (cytochrome b) DNA sequences showed that ''P. simonsi'' represents one independent evolutionary lineage within the genus ''Proechimys'', without clear phylogenetic affinity for any of the six major groups of species.<ref name="Patton1987">{{Cite journal | last=Patton | first=James L. | author-link=James L.
