This is a list of bird species confirmed in the Canadian territory of Northwest Territories. Unless otherwise noted, the list is that of Bird Checklists of the World as of March 2021.^[1] Of the 296 species on the list, 61 are accidental and four were introduced to North America. One species is extinct and another probably is.

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).^[2] Common and scientific names are also those of the Check-list, except that Canadian English spellings are used and the common names of families are from the Clements taxonomy because the AOS list does not include them.

The following tags are used to categorise some species:

• (A) Accidental - a species that rarely or accidentally occurs in Northwest Territories
• (I) Introduced - a species introduced to Northwest Territories as a consequence, direct or indirect, of human actions
