The Snow Mountains robin (Petroica archboldi), also known as the Snow Mountain robin, is a species of bird in the family Petroicidae.

The Snow Mountain robin is only found in Puncak Trikora and the Freeport McMoran Grasberg gold mine, both near Puncak Jaya.

This bird occurs between 3,850-4,150 metres in rocky slopes with no trees, since this bird doesn't occur on or near the tree line, where most other robin species live.

The Snow Mountain robin has slaty-grey plumage, darker wings, a white spot on its forehead, and, most prominently, a large crimson spot on the breast, which makes it easily recognizable.

Generally social birds, Snow Mountain robins live in small groups of a few individuals.
