Gaultheria depressa, commonly known as the mountain snow berry or alpine wax berry, is a small ground hugging shrub of the heath family Ericaceae native to rocky alpine areas of Tasmania, Australia, and New Zealand.

Joseph Dalton Hooker described Gaultheria depressa in 1847 from a collection by Ronald Campbell Gunn at Ben Lomond in Tasmania. The species name is Latin depressa "flat". Two subspecies are recognised, depressa from Tasmania and New Zealand, and novae-zealandiae from New Zealand. Analysis of DNA shows the next closest relative to Gaultheria depressa is the New Zealand species Gaultheria antipoda, which suggests the Australian populations of G. depressa dispersed to Australia from New Zealand. The next closest relative to the two species is the New Zealand species Gaultheria oppositifolia.
In Australia, Gaultheria depressa is a prostrate shrub 10 to 20 cm (4 to 8 in) high and 50 to 150 cm (19.5 to 59 in) across. It grows larger in New Zealand. The small leaves are oval to round and measure 0.5 to 1 cm (0.20 to 0.39 in) in length, and have serrate margins. The small white tubular flowers appear from September to January and are followed by white or red fruit which are around 1 cm in diameter.
In New Zealand, the prostrate habit and dependent fruit shielded by foliage from above suggest it is suited for dispersal by lizards. Furthermore, the ground weta species (Zealandosandrus maculifrons) has been recorded eating the fruit.
It is suitable for rockeries in gardens in temperate climates, and has been available commercially in England. It prefers a well drained acidic soil in part shade. The berries are edible.
