Banksia attenuata, commonly known as the candlestick banksia, slender banksia, or biara to the Noongar people,[3] is a species of plant in the family Proteaceae. Commonly a tree, it reaches 10 m (33 ft) high, but it is often a shrub in drier areas 0.4 to 2 m (1.3 to 6.6 ft) high. It has long, narrow, serrated leaves and bright yellow inflorescences, or flower spikes, held above the foliage, which appear in spring and summer. The flower spikes age to grey and swell with the development of the woody follicles. The candlestick banksia is found across much of the southwest of Western Australia, from north of Kalbarri National Park down to Cape Leeuwin and across to Fitzgerald River National Park.

English botanist John Lindley had named material collected by Australian botanist James Drummond Banksia cylindrostachya in 1840, but this proved to be the same as the species named Banksia attenuata by Scottish botanist Robert Brown 30 years earlier in 1810, and thus Brown's name took precedence. Within the genus Banksia, the close relationships and exact position of B. attenuata is unclear.

The candlestick banksia is pollinated by and provides food for a wide array of animals in summer months. Several species of honeyeater visit the flower spikes, as does the honey possum, which has an important role as a pollinator. It regenerates from bushfire by regrowing from its woody base, known as a lignotuber, or from epicormic buds within its trunk. It can have a lifespan of 300 years. It has been widely used as a street tree and for amenities planting in urban Western Australia, though its large size generally precludes use in small gardens. A dwarf form is commercially available in nurseries.
