Scaevola chamissoniana is a shrub in the family Goodeniaceae with a native range of the Hawaiian Islands, where it is known as the Mountain naupaka or Naupaka kuahiwi.

It is found in wet forests and open areas at elevations of about 1150 feet. It flowers yearround.

It was first described in 1829, by Charles Gaudichaud-Beaupré. The specific epithet, chamissoniana, honours Adelbert de Chamisso, naturalist to the expedition ("around the world, by order of the king").
