The Amazonian antshrike (Thamnophilus amazonicus) is a species of bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is found in every mainland South American country except Argentina, Chile, Paraguay, and Uruguay.

GBIF citizen-science records
It is estimated from how often the Amazonian Antshrike is recorded against all the birds logged in Amacayacu National Natural Park (52 verified sightings from 2019 to 2026), calibrated against known sighting rates.
