The Soldier River is a tributary of the Missouri River, about {{convert|67|mi}} long,U.S. Geological Survey. National Hydrography Dataset high-resolution flowline data. [http://viewer.nationalmap.gov/viewer/ The National Map], accessed March 30, 2011 in western Iowa in the United States. Several portions of the river's course have been straightened and channelized.

The Soldier River rises in southeastern Ida County and flows generally southwestwardly through northwestern Crawford, southeastern Monona and northwestern Harrison Counties, past the towns of Ute, Soldier, Moorhead and Pisgah. It flows into the Missouri River via a diversion channel about 5 mi (8 km) west-northwest of Mondamin.

At Ute, the river collects the East Soldier River, which rises near Schleswig and flows past Charter Oak. The East Soldier River collects the Middle Soldier River, which flows past Ricketts.
