The dusky warbler (Phylloscopus fuscatus) is a leaf warbler which breeds in east Asia. The genus name Phylloscopus is from Ancient Greek phullon, "leaf", and skopos, "seeker" (from skopeo, "to watch"). The specific fuscata is from Latin fuscus "dark".

This warbler is strongly migratory and winters in southeast Asia. It sometimes occurs in North America in Alaska, and has also occurred in California.

This is an abundant bird of taiga bogs and wet meadows. The nest is built low in a bush, and 5-6 eggs are laid. Like most Old World warblers, this small passerine is insectivorous.

The dusky warbler is prone to vagrancy as far as western Europe in October, despite a 3000 km distance from its breeding grounds. It has wintered in Great Britain.

This is a warbler similar in size and shape to a chiffchaff. The adult has an unstreaked brown back and buff underparts. There is a prominent whitish supercilium, and the bill is fine and pointed. The sexes are identical, as with most warblers, but young birds are more olive-tinged above. Like most warblers, it is insectivorous, but will take other small food items, including berries.

The song is a monotonous whistle, and the call is a harsh check. The call is often the first clue that this typically skulking species is present, away from the breeding grounds.
