Helicia grayi, also named Gray's silky oak, is a species of rainforest trees, of north–eastern Queensland, Australia, and constitutes part of the flowering plant family Proteaceae.

Botanists know of them growing naturally only (endemic) in the northern upland rainforests of the Wet Tropics region, from about 400 to 1,200 m (1,300 to 3,900 ft) altitude.[1][2][3][4][5]

As of December 2013 this species has the official, current, Qld government conservation status of "near threatened" species.[6]

They have been recorded growing up to about 15 m (50 ft) tall.[5]
