Boundary County is the northernmost county of the U.S. state of Idaho. As of the 2020 census, the population was 12,056. The county seat and largest city is Bonners Ferry. Boundary County was created by the Idaho Legislature on January 23, 1915. It is so named because it borders Canada, and is therefore the only county in Idaho with an international border. It is also only one of three counties in the United States that borders two states and a foreign country, the others being Coös County, New Hampshire and Erie County, Pennsylvania; these three counties additionally make up the entirety of the international border of their respective states, the only three counties nationwide to do so.
