Banksia lemanniana, commonly known as the yellow lantern banksia or Lemann's banksia, is a species of woody shrub of the family Proteaceae native to Western Australia. It generally grows as an open shrub or small tree to five metres (15 ft) high with stiff serrated leaves, and unusual hanging inflorescences. Flowering occurs over summer, the greenish buds developing into oval flower spikes before turning grey and developing the characteristic large woody follicles. It occurs within and just east of the Fitzgerald River National Park on the southern coast of the state. Banksia lemanniana is killed by bushfire and regenerates from seed.
