Metrosideros parkinsonii, also known as Parkinson's rātā or shrubby rata, is a shrub or small tree endemic to New Zealand.

The name commemorates Sydney Parkinson, Captain James Cook's botanical artist during his first voyage to New Zealand.

Flowers will often appear directly from branches, and can sometimes be hidden behind the foliage.

[1] It naturally occurs in the West Coast of the South Island, from Hokitika to Collingwood, as well as Great Barrier and Little Barrier Islands in the Hauraki Gulf.

Metrosideros parkinsonii is a difficult plant to establish.
