Irvine Stephens Bulloch (June 25, 1842 – July 14, 1898) was an officer in the Confederate Navy and the youngest officer on the famed warship CSS Alabama. He fired its last shot before it was sunk off the coast of France at the end of the American Civil War. He was a half-brother of James Dunwoody Bulloch, who served as a foreign agent in Great Britain on behalf of the Confederacy, in part to arrange blockade runners.
