Cryptocarya bamagana is a rainforest tree that typically grows to a height of 15 m, its stem sometimes buttressed. Its leaves are lance-shaped to elliptic, 80–140 mm long and 30–50 mm wide on a petiole 7-12 mm long. The flowers are arranged in clusters shorter than the leaves and sometimes have an unpleasant odour. The tepals are 1.6–1.7 mm long, the outer anthers 0.8 mm long and 0.6 mm wide, the inner anthers 0.7 mm long and 5 mm wide. Flowering occurs from November to December, and the fruit is a spherical black drupe 9–10 mm long and 9.5–10 mm wide.

Taxonomy
Cryptocarya bamagana was first formally described in 1989 by Bernard Hyland in Australian Systematic Botany, from specimens collected by Hyland collected near Bamaga in 1982.

Distribution and habitat
Bamaga walnut grows near creeks in rainforest at altitudes from 20–100 m above sea level on Cape York Peninsula in Queensland.
