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. It was similar to the Maui alauahio and this species may have reacted similarly to its existing relative, to which it was considered conspecific. This bird was one of several to vanish from Lana'i, along with others such as the Lanai hookbill.
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. The nail in the coffin for the 'alauahio may have been the destruction of forest associated with the construction of the island's main city, Lanai City.
Though not much of its natural history is known, its song was recorded to be a simple chip that was sung at an interval of one chip every three seconds. It disappeared in 1937, the same year as the ʻula-ʻai-hawane disappeared on Hawaii.

El alauahio de Lanai (Paroreomyza montana montana) fue una subespecie de ave paseriforme, endémica de la isla hawaiana de Lanai, de la familia de los fringílidos. Actualmente está extinta, aunque llegó a ser muy común en la isla. A principios del siglo XIX, su población descendió drásticamente, ocasionando su extinción, debido a la deforestación de su hábitat natural.
Era similar al alauahio de Maui, con el que se consideró conespecífico.
Habitó las grandes masas forestales que cubrieron en su momento a la isla de Lanai, pero que debido a la tala de árboles para beneficio humano y a la deforestación, desaparecieron en su mayoría.
Los alauahios de Lanai desaparecieron, principalmente, por culpa de la degradación de su hábitat, de las plantas invasoras llegadas de Europa y demás continentes, de la destrucción de los bosques para la construcción de la única ciudad de la isla (Lanai City) y por su rara necesidad de alimentarse de plantas específicas y autóctonas de la isla para sobrevivir. Aunque comenzó a coexistir con las plantas introducidas, no se consiguió adaptar a ese nuevo ecosistema y acabó desapareciendo. Este pájaro no fue una excepción, ya que desapareció junto con muchos otros, como el Drepano de Lanai que se había extinguido poco tiempo atrás.
