The genus Perisoreus is a very small genus of jays from the Boreal regions of North America and Eurasia from Scandinavia to the Asian seaboard. An isolated species also occurs in north-western Sichuan of China. They belong to the Passerine order of birds in the family Corvidae. Species of Perisoreus jays are most closely related to the genus Cyanopica.{{cite journal |last1=Ericson |first1=Per G.

The genus was introduced by the French zoologist Charles Lucien Bonaparte in 1831.{{ cite journal | last=Bonaparte | first=Charles Lucien | author-link=Charles Lucien Bonaparte | year=1831 | title=Saggio di una distribuzione metodica degli Animali Vertebrati di Carlo Luciano Bonaparte principe di Musignano | journal=Giornale Arcadico di Scienze, Lettre ed Arti | volume=49 | pages=3–77 [42] | url=https://biodiversitylibrary.org/page/10034645 }} The type species was subsequently designated as the Canada jay.{{ cite book | editor1-last=Mayr | editor1-first=Ernst | editor1-link=Ernst Mayr | editor2-last=Greenway | editor2-first=James C.

Alternatively it may be from the Latin peri- "very" or "exceedingly" and sorix, a bird of augury dedicated to Saturn.{{cite web | last=Jobling | first=J.A. | year=2018 | title= Key to Scientific Names in Ornithology | editor1-last=del Hoyo | editor1-first=J. | editor2-last=Elliott | editor2-first=A. | editor3-last=Sargatal | editor3-first=J. | editor4-last=Christie | editor4-first=D.A. | editor5-last=de Juana | editor5-first=E. | work=Handbook of the Birds of the World Alive | publisher=Lynx Edicions | url=https://www.hbw.com/dictionary/definition/perisoreus | access-date=16 May 2018 }}
