Grevillea obtusiflora is a species of flowering plant in the family Proteaceae and is endemic to a small area of eastern New South Wales.

Grevillea obtusiflora is a spreading to erect shrub that typically grows to a height of 0.2–1 m (7.9 in – 3 ft 3.4 in) has many stems.

The flowers are pink to pinkish-red and cream-coloured with a red style, the pistil usually 18–23 mm (0.71–0.91 in) long.

Flowering time varies with subspecies and the fruit is a narrowly elliptic follicle 11–13.5 mm (0.43–0.53 in) long.

[2][3] Grevillea obtusiflora was first formally described in 1830 by Robert Brown in his Supplementum primum Prodromi florae Novae Hollandiae from specimens collected by Allan Cunningham in the Blue Mountains in 1822.
