United States
- northernmost state in the continental U.S.: Minnesota
- northernmost point in the continental U.S.: Northwest Angle, Minnesota, known as "The Angle"
- when negotiating the US-Canadian border following the American Revolution (Treaty of Paris, 1783), negotiators used an inaccurate map of the border of present-day Minnesota and Canada, and thereby included the northwest portion of the Lake of the Woods as the border, while it actually lies within Canadian territory
- thus The Angle is one of six "practical exclaves" of the U.S., as it is only accessible by land via Canada
- in 2010, it's population was 119
