The Leone Mafia family is an Italian-American Mafia criminal organization, originating from Sicily - refered to by Salvatore Leone as "the old country"- whose main base of operations is in Liberty City. They hold various assets in Portland including Cipriani's Restaurante, Sex Club 7, and Joey's Car Repair Shop. The main base of operations however is Salvatore's gentlemen's club, which is in the northeast end of the Saint Mark's district.

Salvatore Leone was the head of the family. He has a son, Joey Leone, who much to Salvatore's dismay is not wed yet. Other people who are in the Leone family include Luigi Goterelli, Toni Cipriani, Mickey Hamfists, and Vincenzo Cilli. Their henchmen don black suits; some with sunglasses, and carry shotguns, Uzis, and pistols. In San Andreas, Leone family hitmen carry AK-47 assault rifles.

The Leone family were also active in Las Venturas, in which they held stakes in the Caligula's Casino with the Sindacco and Forelli Mafia families, as agreed in 1991 (San Andreas). Salvatore Leone would eventually seize total control of the casino in 1992 after the death of Johnny Sindacco with several hits on the Forellis and Sindaccos, only to have his casino robbed later in a heist organized by former ally Carl "CJ" Johnson. It is assumed that because of the great loss of money from the heist, Salvatore abandons his investments in Las Venturas, allowing the Sindaccos to retake the city.

The Family is engaged in a war with the Sindaccos family in Liberty City Stories, winning and in the process taking over Paulie's Revenue Bar as well as the Red Light District and Hepburn Heights, destroying all influence they once had on the island. Three years later in GTA III, the Leone family engage in a small subtle war with the now-weakened Forelli family, killing their capo, Mikey Forelli. In the same year the Leone's get in a full-scale war with the Liberty City Triads after certain businesses in Chinatown stop paying their protection money to the Leone family. The war is long and concludes in 3 of the Triad warlords being killed, as well as the Triad fish factory being destroyed in an explosion.

Claude was seen working for the Leones in GTA III; however, Don Salvatore Leone betrays Claude, ordering him to retrieve a car that has been secretly rigged with explosives. It was later revealed that Salvatore had grown paranoid of Claude, offering Claude's death as a deal to the Colombian Cartel. As a result, Claude assassinates Salvatore as a final gesture to the Leones, in exchange for strengthen ties with the Liberty City Yakuza. Following the death of Salvatore, it is assumed that either his son, Joey Leone, or his capo, Toni Cipriani, will become the new head of the Leone Crime Family.
