The First Battle of Boonville was a minor skirmish of the American Civil War, occurring on June 17, 1861, near Boonville in Cooper County, Missouri. Although casualties were extremely light, the battle's strategic impact was far greater than one might assume from its limited nature. The Union victory established what would become an unbroken Federal control of the Missouri River, and helped to thwart efforts to bring Missouri into the Confederacy. Four battles were fought at Boonville during the Civil War: the first battle forms the main subject of this article, while the others are described below under other battles at Boonville.
