These are lists of invasive species by country or region. 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, threatening agriculture and/or the local biodiversity.
The term invasive species refers to a subset of those species defined as introduced species, for which see List of introduced species.
