• Phylogenetic placement: Passeri: Meliphagida: Meliphagoidea
• Distribution: Southeast Asia, Philippines, Wallacea, Australia and New Guinea, New Zealand
• Number of extant genera: 15
• Number of extant and recently extinct species: 66

Traditional genus-level classification of extant and recently extinct (red letters) Acanthizidae following the AviList checklist v2025. (link) The number of subspecies is given in parentheses. The phylogenetic arrangement is based on Nyári & Joseph (2012) and Marki et al. (2017), and matches that of the BOW Phylogeny Explorer tree v1.6 except for the placement of Gerygone. (link)
