The Faichuk White-eye, Truk White-eye, Great Truk White-eye, or Teardrop White-eye (Rukia ruki) is a species of bird in the Zosteropidae family. It is endemic to the summit of Mount Winipat on Tol, in the Faichuk group of islands within the Chuuk (Truk) atoll in Micronesia.

Its habitat is montane rainforest dominated by the endemic Chuuk Poinsontree. Due to it restricted range on one small mountaintop and the locals' disdain for the native poisontree, it is severely threatened by habitat loss.

Some advocate that it is the only true member of the genus Rukia, or the "Great White-eyes".
