Cettiidae is a newly validated family of small insectivorous songbirds ("warblers"), formerly placed in the Old World warbler "wastebin" assemblage. It contains the typical bush-warblers (Cettia) and their relatives. As common name, cettiid warblers is usually used.

Its members occur mainly in Asia and Africa, ranging into Wallacea and Europe. The monarch-warblers (Erythrocercus), Tit-hylia Pholidornis and Green Hylia (Hylia) are exclusively found in the forests of Africa. The pseudo-tailorbirds, tesias and stubtails, as well as Tickellia and Abroscopus warblers are mostly found in the forests of south and southeastern Asia, with one species reaching as far north as Japan and Siberia. The genus Cettia has the widest distribution of the family, reaching from Western Europe across Asia to the Pacific islands of Fiji and Palau. Most of the species in the genus are sedentary, but the Asian Stubtail is wholly migratory and the Japanese Bush-warbler and Cetti's Warbler are partly migratory over much of their range. A few species, such as the Pale-footed Bush-warbler, are altitudinal migrants.

The species are small, stubby birds. Most have moderately long to long tails, while the stubtails and tesias have tiny tails that do not even emerge past their tail retrices. The group is typically clad in dull plumage, often with a line above the eye. Some, like the monarch-warblers (Erythrocercus), are much different in appearance, having areas of bright yellow plumage. Altogether the Cettiidae are a quite variable group containing many aberrant birds that hitherto had been uncomfortably placed with a wide range of unrelated families. The Megaluridae which contain birds which appear very similar to many cettiids are far more uniform by contrast.

Most live in scrubland and frequently hunt food by clambering through thick tangled growth.

Among the "warbler and babbler" superfamily Sylvioidea, the Cettiidae represent an ancient lineage. As a group, they are probably closest to the Aegithalidae, the long-tailed tits and relatives.
