The Mississippi River is the second longest river in North America, flowing about 2,340 miles from its source at Lake Itasca in Minnesota all the way down to the Gulf of Mexico near New Orleans. Along with its major tributary, the Missouri River, it forms one of the longest river systems on the continent.

For thousands of years, the Mississippi has shaped American life. Native American civilizations built great cities along its banks long before European explorers arrived. Later, the river became a vital highway for trade and transportation: steamboats carried cotton, grain, and passengers up and down its waters, connecting farms and cities from the northern forests to the southern plantations.

The river drains water from 31 states, meaning that rain falling in Montana or Pennsylvania might eventually flow through the Mississippi. Mark Twain made the river famous in his novels about Tom Sawyer and Huckleberry Finn, capturing both its beauty and its role as a pathway to adventure and freedom.

Today, massive barges still transport grain, coal, and other goods along the Mississippi. The river provides drinking water for millions of people and creates rich farmland in its floodplains. Cities like Minneapolis, St. Louis, Memphis, and New Orleans grew powerful partly because they sat along this mighty waterway, helping them control trade and transportation across the heart of America.
