The Maui ʻalauahio, also known as the Maui Nui ʻalauahio or Maui creeper, is a species of Hawaiian honeycreeper. It is endemic to Maui Nui, Hawaii. The name Maui ʻalauahio is somewhat misleading because the species seems to have occurred on most, if not all, parts of the ancient Maui Nui, which includes the present day islands of Maui, Molokaʻi, Lānaʻi, and Kahoʻolawe. There are two subspecies: the Lānaʻi ʻalauahio, P. montana montana, which occurred on Lānaʻi (extinct); and P. montana newtoni which occurs on Maui. The common name refers to both groups.

Hawaiian honeycreepers are a group of small birds endemic to Hawaiʻi. They are members of the finch family Fringillidae, closely related to the rosefinches (Carpodacus), but many species have evolved features unlike those present in any other finch. Their great morphological diversity is the result of adaptive radiation in an insular environment. Many have been driven to extinction since the first humans arrived in Hawaii, with extinctions increasing over the last two centuries following European discovery of the islands, with habitat destruction and especially invasive species being the main causes.
