The Jalisco New Generation Cartel (Spanish: Cártel de Jalisco Nueva Generación, CJNG, Los Mata Zetas and Los Torcidos) is a Mexican criminal group based in Jalisco and headed by Nemesio Oseguera Cervantes ("El Mencho"), one of Mexico's most-wanted drug lords. The CJNG are currently fighting La Nueva Plaza for control of the city of Guadalajara, Jalisco, Los Viagras for the state of Michoacán, Los Zetas for the city of Puebla, the Sinaloa cartel in Tijuana and Baja California, and the Cartel de Juarez in Ciudad Juarez. The CJNG also operates in the states of Nayarit, Colima, and Guanajuato. While this cartel is best known for its fights against the Zetas, it has also been battling La Resistencia for control of Jalisco and its surrounding territories.
Jalisco New Generation Cartel started as one of the splits of Milenio Cartel the other being La Resistencia. La Resistencia accused CJNG of giving up Oscar Valencia (El Lobo) to the authorities and called them Los Torcidos (The Twisted Ones). Jalisco Cartel defeated La Resistencia and took control of Millenio Cartel's smuggling networks. Jalisco New Generation Cartel expanded its operation network from coast to coast in only six months, making it one of the criminal groups with the greatest operating capacity in Mexico as of 2012. The Sinaloa Cartel, led by Joaquín Guzmán Loera (a.k.a. El Chapo), has used the Jalisco New Generation Cartel as its armed wing to fight off Los Zetas in Guzmán's turf and to carry out incursions to other territories like Nuevo Laredo and Veracruz in the past.
Through online videos, the Jalisco New Generation Cartel has tried to seek society's approval and tacit consent from the Mexican government to confront Los Zetas by posing as a "righteous" and "nationalistic" group. Such claims have stoked fears that Mexico, just like Colombia a generation before, may be witnessing the rise of paramilitary drug gangs.
By 2018 the CJNG became the second most powerful cartel in Mexico. By 2018, CJNG co-founder Érick Valencia Salazar and former high ranking CJNG leader Carlos Enrique Sánchez left the cartel and co-founded a rival cartel called the Nueva Plaza Cartel.
