Typhonium brownii, also known as the black arum lily, is a species of plant in the Araceae family that is endemic to Australia.

The species is a deciduous, geophytic, perennial herb, which resprouts annually from a rhizome up to 15 cm long and 2–3 cm in diameter.

The deeply trilobed to triangular leaves are borne on stalks up to 30 cm long.

The inflorescence has a foecal smell and is pollinated by dung beetles; it is enclosed in a 20 cm long spathe, greenish on the outside and deep purple on the inside.
