The Lānaʻi ʻalauahio (Paroreomyza montana montana) is an extinct subspecies of Hawaiian honeycreeper, found on much of the island of Lana'i in the Hawaiian archipelago.

It apparently was common until the early 1900s, when there appeared to have been a steep decline in birds on the island.

The extinction of this species was primarily driven by habitat degradation.

Apparently the many forest plants of Lana'i had become displaced, rare or even extinct as a result of human activity.

With settlers came a host of invasive plants from Europe and other continents.
