A transatlantic telegraph cable is an undersea cable running under the Atlantic Ocean used for telegraph communications. The first was laid across the floor of the Atlantic from Telegraph Field, Foilhommerum Bay, Valentia Island in western Ireland to Heart's Content in eastern Newfoundland. The first communications occurred August 16, 1858, reducing the communication time between North America and Europe from ten days—the time it took to deliver a message by ship—to a matter of minutes. Transatlantic telegraph cables have been replaced by transatlantic telecommunications cables.
Cyrus West Field and the Atlantic Telegraph Company were behind the construction of the first transatlantic telegraph cable.
