This list of bird species introduced to the Hawaiian Islands includes only those species known to have established self-sustaining breeding populations as a direct or indirect result of human intervention. A complete list of all non-native species ever imported to the islands, including those that never became established, would be much longer. In the following list, ^ indicates a species indigenous to the Hawaiian Islands but introduced to an area or areas outside its known native range, * indicates a formerly established population that is now extirpated, and parenthetical notes describe the specific islands where each species is known to be established.
