"Grevillea arenaria" is a shrub which is endemic to the south-west of New South Wales in Australia. It has an erect to spreading habit and grows to between 1 and 3 metres in height. Its leaves are 1.5 to 7 cm long and 3 to 15 mm in width. The flowers, which occur in groups of 2 to 10, are pink, red or orange, with green or yellow at the base and green styles. These occur year round, with a major flourish in spring.

The species was first formally described by botanist Robert Brown in "Transactions of the Linnean Society of London" in 1810.

There are currently two recognised subspecies:
* "G. arenaria" R.Br. subsp. "arenaria"
* "G. arenaria" subsp. "canescens" (R.Br.) Olde & Marriott

A former subspecies, known as "G. arenaria" subsp. montana (R.Br.) McGill., is currently treated as a species in its own right - "G. montana" R.Br.

It occurs on sandy soils in open forests in the Great Dividing Range, its southernmost extent in line with Narooma and its northernmost extent in line with Sydney.
