Solanum aviculare, commonly called Poroporo (New Zealand) or Kangaroo Apple (Australia), is a soft-wooded shrub native to New Zealand and the east coast of Australia.

The leaves and unripe fruit of S. aviculare contain the toxic alkaloid solasodine. S.aviculare is also cultivated in Russia and Hungary for the solasidine which is extracted and used as a base material for the production of steroid contraceptives.
There is some uncertainty whether S. aviculare and S. laciniatum are one or two species. S. aviculare has lighter flowers and is found in the northern part of the North Island of New Zealand, while S. laciniatum has darker purple flowers and is found south of Auckland.

It can grow up to 12 feet tall (4 meters). The leaves are, 8–30 cm long, lobed or entire, with any lobes being 1–10 cm long. The plant is also used as a rootstock for grafting eggplant.
