'''Formicariidae''' is a [[Family (biology)|family]] of smallish [[suboscine]] [[passerine]] birds of subtropical and tropical [[Central America|Central]] and [[South America]] known as antthrushes. They are between {{convert|10|and|20|cm|in|round=0.5|abbr=on}} in length, and are most closely related to the [[ovenbirds]] in the family Furnariidae, and the [[tapaculos]] in the family Rhinocryptidae. The family Formicariidae contains 12 [[species]] in two [[genus|genera]].

These are forest birds that tend to feed on insects at or near the ground. Most are drab in appearance with shades of (rusty) brown, black, and white being their dominant tones. Compared to other birds that specialize in following ants, this family is the most tied to the ground. The long, powerful legs (which lend the birds a distinctive upright posture) and an essentially [[vestigial]] tail aid this lifestyle.

They lay two or three eggs in a nest in a tree, both sexes incubating.
