Protea aurea, the long-bud sugarbush, is a shrub or small tree with a single trunk occurring in mountain fynbos, usually on cool, moist, southern slopes. It is endemic to the Cape Provinces of South Africa.
The flowerheads are solitary and resemble a shuttlecock when open. Fruit is a densely hairy nut. Two subspecies are recognised: subsp. aurea and subsp. potbergensis with the later being rare and restricted to the Potberg.
