Henry Guibor (1823 – October 17, 1899) was a Confederate artillery captain in the American Civil War. Guibor hailed from St. Louis, Missouri, and served in the U.S.-Mexican War. By the Civil War, Guibor was serving as an officer in the state militia artillery battery. Guibor, like many state militiamen, were arrested in the seizure of Camp Jackson in St. Louis by Nathaniel Lyon, but was soon paroled. Guibor eventually traveled southeast from St. Louis and joined Governor Claiborne Fox Jackson's Missouri State Guard. He received command of a battery of four six-pound smoothbore guns. Not long afterward, Guibor's battery saw action in the battles of Carthage, Wilson's Creek, Dry Wood Creek, and Lexington.
