Grevillea hilliana (White Yiel Yiel or White Silky Oak), is a tree which is endemic to New South Wales and Queensland in Australia. Other common names include Grey Oak, Silky Oak, Yiel Yiel, Yill Gill and Hill's Silky Oak. The species grows to between 8 and 30 metres in height. White to pale-green flowers are mainly produced from May to October (late autumn to mid spring) in its native range.
The type specimen was obtained "in the forests at the Pine River of Moreton Bay". The species was formally described in 1857 by botanist Ferdinand von Mueller in Transactions of the Philosophical Institute of Victoria.
