List of impact structures in South America

{{Short description|None}}

{{Earth_Impact_Database_world_map.svg}}

{{GeoGroup}}

This list includes all 11 confirmed impact structures in South America as listed in the Earth Impact Database. These features were caused by the collision of large meteorites or comets with the Earth. For eroded or buried craters, the stated diameter typically refers to an estimate of original rim diameter, and may not correspond to present surface features.

Unconfirmed impact structures

{{main|List of possible impact structures on Earth}}

The following structures are officially considered "unconfirmed" because they are not listed in the Earth Impact Database. Due to stringent requirements regarding evidence and peer-reviewed publication, newly discovered craters or those with difficulty collecting evidence generally are known for some time before becoming listed. However, entries on the unconfirmed list could still have an impact origin disproven.
