The New World warblers or wood-warblers are a group of small, often colorful, passerine birds which make up the family Parulidae and are restricted to the New World. They are not closely related to Old World warblers or to Australian warblers. Most are arboreal, but some, like the ovenbird and the two waterthrushes, are primarily terrestrial. Most members of this family are insectivores.

It is likely that this group originated in northern Central America, where the greatest number of species and diversity between them is found. From there they spread north during the interglacial periods, mainly as migrants, returning to the ancestral region in winter. Two genera, Myioborus and Basileuterus seem to have colonized South America early, perhaps before the two continents were linked, and together constitute most warbler species of that region.

The scientific name for the family, Parulidae, originates from the fact that Linnaeus in 1758 named the northern parula as a tit, Parus americanus, and, as taxonomy developed, the genus name was modified first to Parulus and then to Parula. The family name derives from the name for the genus.

All the warblers are fairly small. The smallest species is the Lucy's warbler (Oreothlypis luciae), at about 6.5 g and 10.6 cm (4.2 in). Which species is the largest depends upon which are to be included in the family. Traditionally, this was considered to be the yellow-breasted chat, at 18.2 cm (7.2 in). Since this may not be a parulid, the Parkesia waterthrushes, the ovenbird, the russet-crowned warbler and Semper's warbler, all of which can exceed 15 cm (5.9 in) and 21 g, might be considered the largest.
