Banksia ser. Quercinae is a valid botanic name for a series of Banksia. First published by Carl Meissner in 1856, the name has had three circumscriptions.

B. ser. Quercinae was first published in 1856, in Carl Meissner's chapter on the Proteaceae in A. P. de Candolle's Prodromus systematis naturalis regni vegetabilis. It was one of four series into which the subgenus Eubanksia was divided. These four series were defined in terms of leaf characters, with series Quercinae containing the species with strongly dentate, cuneate to obovate leaves. As they were defined on leaf characters alone, all of Meissner's series were highly heterogeneous.

The placement and circumscription of B. ser. Quercinae in Meissner's arrangement may be summarised as follows:

Meissner's arrangement was current until 1870, when George Bentham published his arrangement, discarding all four of Meissner's series.

In 1981, Alex George published a thorough revision of Banksia in his classic monograph The genus Banksia L.f. (Proteaceae). He reinstated B. ser. Quercinae, placing it within B. sect. Banksia, and redefining it as containing those species with awned perianths, and beaked follicles. Initially, the series contained three species, but in 1988 George moved B. baueri (Woolly Orange Banksia) into its own series, B. ser. Bauerinae, leaving just B. quercifolia (Oak-leaved Banksia) and B. oreophila (Western Mountain Banksia) in B. ser. Quercinae.
