The Atlantic Blockading Squadron was a unit of the United States Navy created in the early days of the American Civil War to enforce the Union blockade of the ports of the Confederate States. It was formed in 1861 and split up the same year for the creation of the North Atlantic Blockading Squadron and the South Atlantic Blockading Squadron.
