Grevillea incurva is a shrub of the genus Grevillea native to several areas in the Wheatbelt and Goldfields regions of Western Australia. The erect shrub typically grows to a height of 1 to 2.5 metres (3 to 8 ft) with non-glaucous branchlets. It has simple flat linear undissected leaves with a blade that is 10 to 30 millimetres (0.39 to 1.18 in) in length and 0.5 to 1 mm (0.02 to 0.04 in) wide. It blooms in September or October and produces a terminal raceme irregular inflorescence with white or cream flowers. Later it forms an smooth obovoid glabrous fruit that is 7 to 10 mm (0.3 to 0.4 in).
