John Jackson Dickison (March 28, 1816 – August 20, 1902) was an officer in the Confederate States Army during the American Civil War. Dickison is mostly remembered as being the person who led the attack which resulted in the capture of the Union warship USS Columbine in the "Battle of Horse Landing". This was one of the few instances in which a Union warship was captured by land-based Confederate forces during the Civil War and the only known incident in U.S. history where a cavalry unit sank an enemy gunboat. Dickison and his men were victorious in all of his raids against the Union troops in Florida, including his raid in Gainesville what is known as the Battle of Gainesville. Tragedy struck Dickison, when one of his sons, both of whom served under his command, was killed during a raid.
