Banksia serra, commonly known as serrate-leaved dryandra,[2] is a species of shrub that is endemic to Western Australia.

It has broadly linear, serrated leaves, pale yellow flowers in heads of about thirty and egg-shaped follicles.

Banksia serra is a shrub that typically grows to a height of 6 m (20 ft) but does not form a lignotuber.

[2][3] This species was first formally described in 1830 by Robert Brown who gave it the name Dryandra serra and published the description in the Supplementum primum Prodromi florae Novae Hollandiae from specimens collected by William Baxter near King George's Sound in 1829.

[7][8] Banksia serra grows in woodland, forest and mallee-kwongan from the Bow River to Mount Manypeaks.
