This is a comprehensive listing of all the bird species recorded in Acadia National Park, which is in the U.S. state of Maine. The park's avifauna comprise 362 species according to the National Park Service (NPS) as of July 2024.^[1]

This list is presented in the taxonomic sequence of the Check-list of North and Middle American Birds, 7th edition through the 65th Supplement, published by the American Ornithological Society (AOS).^[2] 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.

Unless otherwise noted, all are considered to occur regularly in Acadia National Park as permanent residents, summer or winter visitors, or migrants. The tags below are used to designate the abundance of some species. Acadia includes two large parcels on Mt. Desert Island, part of the Schoodic Peninsula on the mainland, part of Isle au Haut, and all or part of several smaller islands. Therefore, some species which are common or abundant on the Maine coast as a whole can be in the "less than common" categories within the Park boundaries.

• (R) Rare - "usually seen only a few times each year" (26 species)
• (Unc) Uncommon - "likely to be seen monthly in appropriate habitat and season and may be locally common" (16 species)
• (O) Occasional - "occur in a park at least once every few years, varying in numbers, but not necessarily every year" (14 species)
• (Unk) Unknown (24 species)
• (Hist) Historical - "Species' historical occurrence in park is documented. Designation of what constitutes "historical" is a judgment call" (27 species)
• (NC) Unconfirmed - "Attributed to the park based on weak ("unconfirmed record") or no evidence" (114 species)
• (I) Introduced - a species introduced to North America by the actions of man, either directly or indirectly (five species)
• (E) Extinct - a recent species that no longer exists (four species)
