Located in territory that had long been occupied by the Lakota Sioux, Mobridge was founded by European Americans in 1906 following construction of the Chicago, Milwaukee, St. Paul and Pacific Railroad through here. The town was named Mobridge for its railroad designation, a contracted form of Missouri Bridge, after the original railroad bridge over the Missouri River. The bridge was demolished by the Corps of Engineers in the early 1960s and replaced by a higher bridge due to the construction of the Oahe Dam.
