The Mississippi River is the second longest river in the United States, with a length of 2,340 miles (3,770 km) from its source in Lake Itasca in Minnesota to its mouth in the Gulf of Mexico. The longest river in the United States is a Mississippi tributary, the Missouri River, measuring 2,540 miles (4,090 km).
The Mississippi River is part of the Jefferson-Missouri-Mississippi river system, which is the largest river system in North America and among the largest in the world: by length (3,900 miles (6,300 km)), it is the fourth longest, and by its average discharge of 572,000 cu ft/s (16,200 m³/s), it is the tenth largest river.
The name Mississippi is derived from the Ojibwe word misi-ziibi (“Great River”) or gichi-ziibi (“Big River”) at its headwaters.
The Quad Cities is the only bend where the Mississippi River flows East to West instead of North to South.
