Grevillea gariwerdensis is a species of the plant genus Grevillea. It is endemic to Victoria in Australia. The species grows as a low, suckering shrub, between 0.3 and 1 metre in height. Flowers usually appear between October and January (mid spring to mid summer) in its native range. These have perianths and styles which are white to pink. It is very similar in appearance to both Grevillea micrantha and Grevillea parviflora. The name Grevillea linearifolia has been misapplied to this species in the past.
