This list of birds of North Dakota includes species documented in the U.S. state of North Dakota. The list is derived from Checklist of North Dakota Birds produced in April 2021 by the North Dakota Game and Fish Department (NDGFD). The basic NDGFD list contains 420 confirmed and extant species, two extinct species. Three additional species have been added from the North Dakota Bird Records Committee (NDBRC) review list with some additions from Avibase. The combined lists contain 420 species. Of them, 194 and a subspecies are on the review list (see below). The NDGFD list considers 44 species to be accidental, and eight species have been introduced to North America.
