List of invasive species in Europe

This is a list of invasive species in Europe. A species is regarded as invasive if it has become introduced to a location, area, or region where it did not previously occur naturally (i.e., is not a native species) and becomes capable of establishing a breeding population in the new location. An invasive species will be one that thrives in its new environment and negatively influences the ecology and biodiversity of that ecosystem.

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 cannot be considered to be invasive, and does not belong on this list.
