John Milton Brannan (July 1, 1819 – December 16, 1892) was an American military officer who served with distinction in the Mexican–American War as a United States Army artillery officer and as a Union Army brigadier general of United States Volunteers in the American Civil War. Brannan held command of the Department of Key West at Fort Zachary Taylor, Florida, part of the Union effort to hold federal installations within Confederate territories early in the war. Later, and most notably, he served as a division commander of the Union XIV Corps at the Battle of Chickamauga in 1863.

Brannan was scandalized by the highly publicized disappearance of his first wife, Eliza Crane Brannan, daughter of Colonel Ichabod B. Crane, in 1858; she mysteriously disappeared after taking a ferry from Staten Island to Lower Manhattan and was initially presumed to have committed suicide or been murdered, but it was later discovered that she had secretly fled to Europe and married another United States Army artillery officer, First Lieutenant Powell T. Wyman.
