Isopogon latifolius is a shrub of the family Proteaceae that is endemic to the southwest botanical province of Western Australia.

[3] The species was first formally described by botanist Robert Brown in 1830,[2] based on material collected by William Baxter at King George's Sound.

[5] In 1891, German botanist Otto Kuntze published Revisio generum plantarum, his response to what he perceived as a lack of method in existing nomenclatural practice.

[11] I. latifolius can take over five years to flower from seed, meaning it can be locally eradicated by too-frequent fire intervals.

[12] The showiest of the isopogons, I. latifolius can be grown in regions with low humidity and in positions with good drainage, but will die readily if these conditions cannot be met.
