Pseudopanax arboreus or five finger (Māori: puahou or whauwhaupaku), is a New Zealand native tree belonging to the family Araliaceae.

It is one of New Zealand's more common native trees, being found widely in bush, scrub and gardens throughout both islands.

The compound leaves with five to seven leaflets, hence the common name, are very characteristic of the tree and easily recognized.

Calyx truncate or obscurely 5-toothed; flowers 5mm in diameter, sweet-scented; petals 5, white to pink flushed, ovate to triangular, acute; stamens 5; ovary 2-loculed, each containing 1(-2) ovules; style branches 2, spreading.

Pseudopanax arboreus is a host species for the caterpillar of the endemic North Island moth Declana atronivea.
