The Little Blue River is a 245-mile-long (394 km)[1] river in southern Nebraska and northern Kansas that was used by Pony Express horseback riders. Ridgelines of this historic watershed defined the wagon train routes first used by Oregon Trail Emigrants.
The Little Blue rises just south of Minden in Kearney County, Nebraska. It flows east-southeast past Hebron and Fairbury, Nebraska. It joins the Big Blue River at Blue Rapids, Kansas.
Various other rivers also have the name "Little Blue River".
