The olomaʻo (Myadestes lanaiensis) is a small, dark solitaire endemic to Maui, Lānaʻi and Molokaʻi in the Hawaiian Islands. It is listed as Critically Endangered or possibly extinct. The last definitive sighting occurred on Oahu in the 1850s, on Lanai in 1933, and on Molokaʻi in 1980 in the Kamakou Preserve.
The extinct ʻāmaui, either a subspecies of M. lanaiensis or a distinct species (as M. woahensis), was endemic to Oʻahu.
