The Eurasian jay was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his "Systema Naturae" under the binomial name "Corvus glandarius". Linnaeus specified the locality as "Europa" but this was restricted to Sweden by Ernst Hartert in 1903. The Eurasian jay is now one of three species placed in the genus "Garrulus" that was established in 1760 by the French zoologist Mathurin Jacques Brisson. The genus name "Garrulus" is a Latin word meaning "chattering", "babbling" or "noisy". The specific epithet "glandarius" is Latin meaning "of acorns".
