List of extreme points of U.S. states and territories

Extreme points are portions of a region which are further north, south, east, or west than any other. This is a list of extreme points in U.S. states, territories, and the District of Columbia.^[1]

Although many borders were initially defined by treaty or other agreement to be along a specific line of latitude or longitude, inaccuracies with surveying equipment/techniques caused the surveyed lines to deviate slightly from the true boundaries. Even as equipment/techniques improved, the initial surveyed line still remains the official border,^[2] which is why the extreme points may be either side of the agreed-upon line.

The 49th parallel was agreed to be the border between the United States and British North America (later Canada) from Lake of the Woods to the Strait of Juan de Fuca in the Treaty of 1818 and Oregon Treaty. However, the true boundary line as surveyed deviates several seconds from the true parallel, as seen in this significantly exaggerated depiction
