Banksia ser. Dryandroideae is a taxonomic series in the plant genus Banksia. First published by Carl Meissner in 1856, the name has had two circumscriptions. As presently circumscribed it is monotypic, containing only B. dryandroides.

B. ser. Dryandroideae 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 Dryandroideae containing the species with leaves divided into lobels. As they were defined on leaf characters alone, all of Meissner's series were highly heterogeneous.

The placement and circumscription of B. ser. Dryandroideae 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). Though he did not accept Meissner's definition of B. ser. Dryandroideae, he felt that "Banksia dryandroides appears to provide a link between the Spicigerae and the Abietinae but is sufficiently distinct from both to be placed in its own series." He therefore resurrected B. ser. Dryandroideae as a monotypic series containing B. dryandroideae alone, placing it in Bentham's B. sect. Oncostylis, which was defined as containing the species with hooked styles. Since Meissner had not designated a type species for the series, George also declared B. dryandroides to lectotype.
