The Beltrán-Leyva Cartel (Spanish: Cártel de los Beltrán Leyva) is a Mexican drug cartel and organized crime syndicate founded by the four Beltrán Leyva brothers: Marcos Arturo, Carlos, Alfredo and Héctor.
The cartel is responsible for cocaine transportation and wholesaling, marijuana production and wholesaling, and heroin production and wholesaling, controls numerous drug trafficking corridors, and engages in human smuggling, money laundering, extortion, kidnapping, murder and gun-running. The Beltrán Leyva brothers, who were formerly aligned with the Sinaloa Cartel, are now allies of Los Zetas.
