Haleakala Sandalwood or Iliahi (Santalum haleakalae) is a small (2 to 6 m) tree endemic to Maui, restricted to the upper elevations (from 1,900 to 2,700 m) of Haleakala volcano (primarily within the crater of the volcano and on its western and southern flanks). It inhabits dry alpine and subalpine shrublands and forests on old lava flows, volcanic ash, or cinder. It is considered to be rare; its global ranking is "critically imperiled." This individual was found at about 9,000 feet on a southwest-facing slope of Haleakala (south Maui).

From about 1810 to 1830 the fragrant heartwood of Hawaiian sandalwood was exported to China in large quantities. It is not known to what extent the sandalwood trade affected Santalum haleakalae. For most of the 1900s much of the alpine and subalpine zone of Haleakala was overrun with goats. In the 1980s a perimeter fence was built along the Haleakala National Park boundary line to exclude the goats. The park is now free of goats, but the sandalwood trees that grow outside the fence line continue to be threatened by them. Other threats to the species are feral pigs and alien plants.
