Grevillea tenuiflora, commonly known as the round leaf grevillea, is a shrub of the genus Grevillea native to an area in the Wheatbelt and Goldfields-Esperance regions of Western Australia. The erect to spreading shrub typically grows to a height of 0.5 to 2 metres (1.6 to 6.6 ft) and has non-glaucous branchlets. It has simple, dissected and tripartite leaves with a blade that is 25 to 50 millimetres (0.98 to 1.97 in). It blooms between June and November and produces an axillary or terminal raceme irregular inflorescence with white or pink flowers and white or pink styles. Later it forms rugose oblong or ellipsoidal glabrous fruit that are 9 to 13 mm (0.4 to 0.5 in) long.
