Banksia speciosa, commonly known as the showy banksia, is a species of large shrub or small tree in the family Proteaceae. It occurs on the south coast of Western Australia between Hopetoun (33°57′ S) and the Great Australian Bight (approximately 33° S 130° E), growing on white or grey sand in shrubland. Reaching up to 8 m (26 ft) in height, it is a single-stemmed plant that has thin leaves with prominent triangular "teeth" along each margin, which are 20–45 cm (7.9–17.7 in) long and 2–4 cm (0.8–1.6 in) wide. The prominent cream-yellow flower spikes known as inflorescences appear throughout the year. As they age they develop up to 20 follicles each that store seeds until opened by fire. Banksia speciosa. Though widely occurring, it is highly sensitive to dieback and large populations of plants have succumbed to the disease.

Collected and described by Robert Brown in the early 19th century, Banksia speciosa is classified in the series Banksia within the genus. Its closest relative is B. baxteri. Banksia speciosa plants are killed by bushfire, and regenerate from seed. The flowers attract nectar- and insect-feeding birds, particularly honeyeaters, and a variety of insects. In cultivation, Banksia speciosa grows well in a sunny location on well-drained soil in areas with dry summers. It cannot be grown in areas with humid summers, though it has been grafted onto Banksia serrata or B. integrifolia.
