The Continental Iron Works was an American shipbuilding and engineering company founded in Greenpoint, Brooklyn, in 1861 by Thomas F. Rowland. It is best known for building a number of monitor warships for the United States Navy during the American Civil War, most notably the first of the type, USS Monitor. Monitor's successful neutralization of the Confederate ironclad CSS Virginia in the 1862 Battle of Hampton Roads—the world's first battle between ironclad warships—would come to heavily influence American naval strategy both during and after the war.
