Grevillea leptobotrys is a shrub of the genus Grevillea native to an area in the Wheatbelt and South West regions of Western Australia. The sprawling prostrate non-lignotuberous shrub typically grows to a height of 0.1 to 0.5 metres (0.3 to 1.6 ft) and has non-glaucous branchlets. It has simple flat linear leaves with a blade that is 30 to 1,290 millimetres (1 to 51 in) in length and 10 to 20 mm (0.39 to 0.79 in) wide. It blooms from October to December and produces a terminal raceme irregular inflorescence with pink flowers. Later it forms a smooth obovoid glabrous fruit that is 9 to 14 mm (0.4 to 0.6 in).
