Another 18 and a species pair are considered unsubstantiated. One species is endemic to the state. One species has been added as a result of a split enacted in June 2021.

The list of birds of Alaska includes every wild bird species recorded in the U.S. state of Alaska, based on the list published by the Alaska Checklist Committee. As of January 2022, there were 534 species on the official list. Of them, 55 are considered rare, 149 are casual, and 79 are accidental, all as defined below. Another 18 and a species pair are considered unsubstantiated. One species is endemic to the state. One species has been added as a result of a split enacted in June 2021. Only birds that are considered to have established, self-sustaining, wild populations in Alaska are included on this list. This means that birds that are considered probable escapees, although they may have been sighted flying free in Alaska, are not included. Species which the Checklist Committee considers to depend entirely on human feeding, such as rock pigeon, are also not included. This list is presented in the taxonomic sequence of the Check-list of North and Middle American Birds, 7th edition through the 62nd Supplement, published by the American Ornithological Society (AOS). Common and scientific names are also those of the Check-list, except that the common names of families are from the Clements taxonomy because the AOS list does not include them. The following codes and definitions (except En) are used by the Alaska Checklist Committee to annotate some species:
* (R) = Rare - "Annual or possibly annual in small numbers; most such species occur at the perimeter of Alaska, in season; a few are scarce residents"
* (C) = Casual - "Not annual; these species are beyond the periphery of annual range, but recur in Alaska at irregular intervals, usually in seasonal and regional patterns"
* (A) = Accidental - "One or two Alaska records, or none in the last 30 years"
* (U) = Unsubstantiated - "attributed to Alaska without specimen or photo substantiation"
* (En) = Endemic - A species found only in Alaska (except as a vagrant elsewhere)
