List of invasive species in North America

This is a list of invasive species in North America. A species is regarded as invasive if it has been introduced by human action to a location, area, or region where it did not previously occur naturally (i.e., is not a native species), becomes capable of establishing a breeding population in the new location without further intervention by humans, and becomes a pest in the new location, directly threatening agriculture or the local biodiversity.

The term invasive species refers to a subset of those species defined as introduced species. If a species has been introduced, but remains local, and is not problematic to agriculture or to the local biodiversity, then it is not considered to be invasive, and does not belong on this list.
