Grevillea acropogon is a shrub which is endemic to the south-west of Western Australia. It has a prostrate or erect habit, growing to a maximum height of 1.8 metres, with leaves which are 15 to 30 mm long. Red flowers appear in racemes between July and September in its native range. The species was first formally described in 2000 in the Flora of Australia, based on plant material collected near Lake Unicup in 1996. It occurs among medium-sized trees in stony or rocky soils.
