Acrothamnus colensoi, also known as Colenso's mingimingi or mountain heath, is a species of plant in the family Ericaceae endemic to New Zealand.

It can be found in both the lower North and eastern South Islands, in scrubland, tussock grassland, and rocky fellfield.

[2] It had been treated as A. suaveolens (a species now considered endemic to Borneo) but was separated by an examination of DNA and chromosome number.

[7] Its berries are 4–5 mm in diameter, globose, fleshy, and glossy; colours range between white, pink, red, and crimson to almost black.

[8] In the South Island it can be found in drier eastern mountains of Marlborough and Canterbury, locally in Otago and rarely in northern Southland.

[6] Its habitat is generally montane to low-alpine (600–1600 m), extending to lower altitudes in the southern part of its range.
