Joseph Magliocco (born Giuseppe Magliocco; Italian pronunciation: [dʒuˈzɛppe maʎˈʎɔkko]; June 29, 1898 – December 28, 1963), also known as "Joe Malayak" and "Joe Evil Eye", was a Sicilian-born New York mobster and the boss of the Profaci crime family (later to become the Colombo crime family) from 1962 to 1963.

In 1963, Magliocco participated in an audacious attempt with Joseph Bonnano to kill other family bosses and take over the Mafia Commission.

Magliocco was born in Portella di Mare, a frazione in the comune of Misilmeri, in the province of Palermo, in Sicily.

Despite weighing over 300 pounds, Magliocco was described as being very energetic and decisive in his work and physical gestures, someone who exuded danger and confidence.

On December 5, 1928, Magliocco and Profaci attended a meeting of New York mobsters at the Statler Hotel in Cleveland, Ohio.

The main topic was dividing the Brooklyn territory of the recently murdered boss Salvatore D'Aquila without causing a gang war.

By the end of the meeting, Profaci had received a share of the open territory, and named Magliocco as his second-in-command—a post he would hold for the next 34 years.

[5] Larry Gallo survived a strangulation attempt in the Sahara club of East Flatbush by Carmine Persico and Salvatore "Sally" D'Ambrosio after a police officer intervened.

[11] Afraid that the other New York families viewed him as weak, Magliocco increased the tempo of violence against the Gallo faction.

[12] In turn, car bombs, drive-by shootings, and other murder attempts were made against Magliocco men such as Carmine Persico and his enforcer, Hugh McIntosh.

[13] Magliocco was assigned the task of killing Lucchese and Gambino, and gave the contract to one of his top hit men, Joseph Colombo.

The Commission spared Magliocco's life, but forced him to retire as Profaci family boss and pay a $50,000 fine.

[13] On December 28, 1963, Joseph Magliocco died of a heart attack at Good Samaritan Hospital Medical Center in West Islip, New York.
