Grallariidae is a family of smallish suboscine passerine birds of subtropical and tropical Central and South America known as antpittas.

Most are drab in appearance with shades of (rusty) brown, black, and white being their dominant tones.

The long, powerful legs (which lend the birds a distinctive upright posture) and an essentially vestigial tail aid this lifestyle.

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.

It is based on a large molecular phylogenetic study of the suboscines by Michael Harvey and collaborators that was published in 2020.
