Grevillea johnsonii, commonly known as Johnson's grevillea or Johnson's spider flower, is a species of flowering plant in the family Proteaceae and is endemic to New South Wales. It is a shrub with divided, needle-like leaves and red to orange flowers, and grows in rocky places.
Grevillea johnsonii is endemic to New South Wales where it grows in rocky places on sandstone. The National Herbarium of New South Wales gives its distribution as "chiefly in the Goulburn and Capertee River catchments with a record from the Brogo River not verified". The Australian Native Plants Society suggests that the "common garden red and cream form" occurs near the Brogo River, whereas the orange-flowered form "grows naturally in the Goulburn River catchment at Cox's Gap and several other close by areas". The species grows natively at an altitude of 400–700 m (1,300–2,300 ft), where the annual rainfall is 600–700 mm (24–28 in).
