Banksia acanthopoda is a species of shrub in the Proteaceae family. It grows as a small spreading shrub to 2 m (6 1⁄2 ft) high and has prickly leaves and yellow composite flower heads, called inflorescences, composed of 50 to 60 individual yellow flowers. Endemic to Western Australia, it occurs only in a few populations in the vicinities of Woodanilling, Katanning and Darkan. Because of its rarity, it is classed as "Priority Two" conservation flora by Western Australia's Department of Environment and Conservation.
