The accentors are a genus of birds in the family Prunellidae, which is endemic to the Old World. This small group of closely related passerines are all in the genus Prunella. All but the dunnock and the Japanese accentor are inhabitants of the mountainous regions of Europe and Asia; these two also occur in lowland areas, as does the Siberian accentor in the far north of Siberia. These birds are not strongly migratory, but they will leave the coldest parts of their range in winter and make altitudinal movements.

The dunnock is a small passerine, or perching bird, found throughout temperate Europe and into Asian Russia. Dunnocks have also been introduced into New Zealand. It is by far the most widespread member of the accentor family; most other accentors are limited to mountain habitats. Other common names of the dunnock include: hedge accentor, hedge sparrow, hedge warbler, and titling.
