Acanthizidae—sometimes called Australian warblers—are a family of passerine birds which includes gerygones, thornbills Acanthiza, and scrubwrens Sericornis. The family Acanthizidae consists of small to medium passerine birds, with a total length varying between 8 and 19 centimetres. They have short rounded wings, slender bills, long legs, and a short tail. Most species have olive, grey, or brown plumage, although some have patches of a brighter yellow. The weebill is the smallest species of acanthizid, and the smallest Australian passerine; the largest is the pilotbird.

A passerine is any bird of the order Passeriformes which includes more than half of all bird species. Sometimes known as perching birds, passerines generally have an anisodactyl arrangement of their toes, which facilitates perching.
