SS Sirio was an Italian merchant steamer that had a shipwreck off the eastern Spanish coast on August 4, 1906, causing the deaths of at least 150 Italian and Spanish emigrants bound for Brazil, Uruguay, and Argentina. The shipwreck gained notoriety because the captain, Giuseppe Piccone, abandoned ship at the first opportunity. The wreck had a profound effect on communities in northern Italy and was remembered in popular songs of the era.
