Cordyline banksii (forest cabbage tree, tī ngahere) is a monocot tree endemic to New Zealand. The specific epithet banksii refers to the 18th-century botanist Joseph Banks.
Cordyline banksii tolerates a wide variety of habitats. It is common in coastal, lowland, and lower montane forests in the North Island, widespread in the northern half of the South Island and Westland as far south as Haast. It has occasionally been reported from coastal Fiordland, but these sightings are unsubstantiated. It also occasionally occurs in subalpine regions in the South Island. In shrublands it occurs with Cordyline pumilio and may form hybrids with it.
