The two rivers that partially form the eastern boundary of the United States are the Mississippi River and the St. Lawrence River. The Mississippi River flows southward from Minnesota to the Gulf of Mexico, serving as a significant boundary for several states. The St. Lawrence River, situated in the northeastern part of the country, forms part of the boundary between the United States and Canada.
