The red swamp banksia or waterbush (Banksia occidentalis) is a species of shrub or small tree in the plant genus Banksia. It occurs on the south coast of Western Australia in three disjunct populations: at Augusta, around Albany and in the Esperance area.

A 1980 field study at Cheyne beach showed it to be pollinated by the New Holland honeyeater and white-cheeked honeyeater.^[1]

Seeds do not require any treatment, and take 21 to 47 days to germinate.^[2]

The species was observed to be in cultivation in England in the gardens of Chiswick House in 1834.^[3]
