'''Grallariidae''' is a family of smallish suboscine passerine birds of subtropical and tropical Central and South America known as '''antpittas'''. They are between {{convert|10|and|20|cm|in|round=0.5|abbr=on}} long, and are related to the antbirds, Thamnophilidae, and gnateaters, Conopophagidae.
The antpittas were formerly placed in the family Formicariidae. Beginning in 2002 a series of molecular genetic studies found that Formicariidae, as then defined, was non-monophyletic.<ref name=Irestedt>{{Cite journal | last1=Irestedt | first1=M. | last2=Fjeldså | first2=J. | last3=Johansson | first3=U.S. | last4=Ericson | first4=P.G.P. | date=2002 | title=Systematic relationships and biogeography of the tracheophone suboscines (Aves: Passeriformes) | journal=Molecular Phylogenetics and Evolution | volume=23 | issue=3 | pages=499–512 | doi=10.1016/S1055-7903(02)00034-9| pmid=12099801 | bibcode=2002MolPE..23..499I }}</ref><ref>{{Cite journal | last=Chesser | first=R.

These are forest birds that tend to feed at or near the ground. Many are specialist ant followers. Their long, powerful legs (which lend the birds a distinctive upright posture) and an essentially vestigial tail aid this behaviour. Most are drab in appearance with shades of rusty, brown, black, and white being their dominant tones.
The antpittas are sexually monomorphic; they resemble the true pittas in that they are virtually tailless; they hop like some thrushes, and are much easier to hear than see—although their vocalizations may be rather atypical for perching birds.

==Taxonomy== The following cladogram shows the phylogeny of the antipitta family. It is based on a large molecular phylogenetic study of the suboscines by Michael Harvey and collaborators that was published in 2020. The three species in the genus ''Myrmothera'' were found to be embedded in the genus ''Hylopezus''.<ref name=harvey>{{Cite journal | last1=Harvey | first1=M.G. | display-authors=etal | date=2020 | title=The evolution of a tropical biodiversity hotspot | journal=Science | volume=370 | issue=6522 | pages=1343–1348 | doi=10.1126/science.aaz6970 | pmid=33303617 | bibcode=2020Sci...370.1343H | hdl=10138/329703 | hdl-access=free }} A high resolution version of the phylogenetic tree in Figure 1 is available from the first author's website [http://www.harveybirdlab.org/docs/Harveyetal2020_Fig1_tree_HiRes.pdf here].</ref> The species are those recognised by the International Ornithologists' Union (IOC).<ref name=ioc>{{cite web| editor1-last=Gill | editor1-first=Frank | editor1-link=Frank Gill (ornithologist) | editor2-last=Donsker | editor2-first=David | editor3-last=Rasmussen | editor3-first=Pamela | editor3-link=Pamela Rasmussen | date=January 2023 | title=Antthrushes, antpittas, gnateaters, tapaculos, crescentchests | work=IOC World Bird List Version 13.1 | url=http://www.worldbirdnames.org/bow/antthrushes/ | publisher=International Ornithologists' Union | access-date=5 March 2023 }}</ref> {{clade | style=font-size:100%;line-height:100% |label1='''Grallariidae''' |1={{Clade |1=''Grallaria'' – 45 species |2={{clade |1=''Cryptopezus'' – speckle-breasted antpitta |2={{clade |1=''Grallaricula'' – 10 species |2=''Hylopezus'' – 6 species and ''Myrmothera'' – 6 species }} }} }} }}
