Grevillea glossadenia is a small to medium shrub in the protea family, native to northeastern Queensland, Australia. It grows about 1–2 meters tall and has elliptic leaves 50–120 mm long and 20–35 mm wide, with edges that curve downward and a silky-haired underside. The flowers are deep yellow-orange to orange-red, arranged in small clusters at leaf axils or branch tips, with a pistil about 26–32 mm long. It can flower most months, mainly from April to August, and the fruit is a small oval pod (follicle) 10–14 mm long.

The plant was first formally described in 1975 by Donald McGillivray from specimens collected in 1972 by Bernard Hyland near Bakerville (near Irvinebank).

Grevillea glossadenia grows in woodland or open forest between Walkamin, Irvinebank and Herberton. It is listed as Near Threatened on the IUCN Red List and Vulnerable under Australian and Queensland conservation laws, due to its limited range and habitat threats from mining and changing fire regimes. The population is not highly fragmented and appears stable for now.

For gardeners, it is grown as an ornamental plant for small gardens, in a sunny, well-drained spot. It is frost hardy and tolerates humidity. A cultivar called Grevillea 'Orange Marmalade' was created by crossing this species with Grevillea venusta.
