The olive-backed flowerpecker (Prionochilus olivaceus) is a species of bird in the family Dicaeidae.

From below, somewhat similar to Pygmy Flowerpecker with its dark sides, but Olive-backed has a golden-olive back.

Voice includes a sweet, high-pitched upslurred whistle and a sharp “tsik!” call, sometimes run together in a rapid series.

Nesting has been recorded in August and birds in breeding condition with enlarged have been collected in May.

The IUCN Red List has assessed this bird as least-concern species although it is uncommon in all parts of its range and is poorly known.
