The Biak leaf warbler is a small Old World warbler in the family Phylloscopidae, restricted to Biak Island off the northern coast of Papua, Indonesia. It forages actively among leaves and twigs, where its high-pitched calls often reveal its presence before it is seen. Like many island leaf warblers, it has been subject to ongoing taxonomic study and potential splits from wider island complexes.
