# List of tributaries of the Missouri River

Tributaries of the Missouri River, a major river in the central United States, are listed here in upstream order. These lists are arranged into river sections between cities or mouths of major tributaries for ease of navigation. Two large tributaries (the Platte and Yellowstone) have their own separate lists because they would be too lengthy to include in part of another section.
Data is derived from U.S. Geological Survey (USGS) topographical maps and the USGS National Map.
