Michael Costa (died 1948) was an Italian-American mobster and a caporegime in the Stracci crime family. During the Five Families War, he smuggled arms from the Canadian border for use against the Corleone crime family. In order to halt his schemes, Rocco Lampone sent Aldo Trapani to assassinate Costa at his railyard hideout, and Trapani struck and killed Costa with his car.
