Notable criminally-active gangs in Mexico include:
Los Zetas is a Mexican criminal syndicate, known as one of the most dangerous of Mexico's drug cartels. They are known for engaging in brutally violent "shock and awe" tactics such as beheadings, torture, and indiscriminate murder. While primarily concerned with drug trafficking, the organization also ran profitable sex and gun rackets. Los Zetas also operated through protection rackets, assassinations, extortion, kidnappings and other illegal activities. The organization was based in Nuevo Laredo, Tamaulipas, directly across the border from Laredo, Texas. The origins of Los Zetas date back to the late 1990s, when commandos of the Mexican Army deserted their ranks and began working as the enforcement arm of the Gulf Cartel. In February 2010, Los Zetas broke away and formed their own criminal organization, rivalling the Gulf Cartel.
The Juárez Cartel, also known as the Vicente Carrillo Fuentes Organization, is a Mexican drug cartel based in Ciudad Juárez, Chihuahua, across the Mexico—U.S. border from El Paso, Texas. The cartel is one of several drug trafficking organizations that have been known to decapitate their rivals, mutilate their corpses and dump them in public places to instill fear not only in the general public but also in local law enforcement and their rivals, the Sinaloa Cartel. Its current known leader is Juan Pablo Ledezma. The Juárez Cartel has an armed wing known as La Línea, a Juárez street gang that usually performs the executions and is now the cartel’s most powerful and leading faction. It also uses the Barrio Azteca gang to attack its enemies.
The Mexican drug war is an ongoing asymmetric armed conflict between the Mexican government and various drug trafficking syndicates. When the Mexican military intervened in 2006, the government's main objective was to reduce drug-related violence. The Mexican government has asserted that their primary focus is dismantling the cartels and preventing drug trafficking. The conflict has been described as the Mexican theater of the global war on drugs, as led by the United States federal government.
Los Negros was a criminal organization that was once the armed wing of the Sinaloa Cartel and after a switch of alliances, became the armed wing of the Sinaloa splinter gang, the Beltrán-Leyva Cartel. In 2010 it went independent and had been contesting the control of the Beltrán-Leyva Cartel. It was then the criminal paramilitary unit of Édgar Valdez Villarreal in Mexico. Valdez was arrested on August 30, 2010, near Mexico City. Los Negros was led by Valdez at the time they merged with the Sinaloa Cartel.
The timeline of some of the most relevant events in the Mexican drug war is set out below. Although violence between drug cartels had been occurring for three decades, the Mexican government held a generally passive stance regarding cartel violence through the 1980s and early 2000s.
La Familia Michoacana, La Familia, is a Mexican drug cartel and organized crime syndicate based in the Mexican state of Michoacán. They are known to produce large amounts of methamphetamine in clandestine laboratories in Michoacan. Formerly allied to the Gulf Cartel—as part of Los Zetas—it split off in 2006. The cartel was founded by Carlos Rosales Mendoza, a close associate of Osiel Cárdenas. The second leader, Nazario Moreno González, known as El Más Loco, preached his organization's divine right to eliminate enemies. He carried a "bible" of his own sayings and insisted that his army of traffickers and hitmen avoid using the narcotics they produce and sell. Nazario Moreno's partners were José de Jesús Méndez Vargas, Servando Gómez Martínez and Enrique Plancarte Solís, each of whom has a bounty of $2 million for his capture, and were contesting the control of the organization.

It controlled numerous drug trafficking corridors, and engaged in human smuggling, money laundering, extortion, kidnapping, murder and gun-running.
The Milenio Cartel, or Cártel de los Valencia, was a Mexican criminal organization based in Michoacán. It relocated to Jalisco in the early 2000s. The Jalisco New Generation Cartel was born from the splintering of the Milenio Cartel.

The Jalisco New Generation Cartel or CJNG, is a Mexican criminal syndicate, based in Jalisco and headed by Nemesio Oseguera Cervantes. The cartel has been characterized by extreme violence and public relations campaigns.

The cartel has been noted for cannibalizing some victims during the training of new sicarios or members, as well as using drones and rocket-propelled grenades to attack enemies.
Guerreros Unidos is a Mexican criminal syndicate in the states of Southern Mexico.
Grupos de autodefensas or Policía Comunitaria or Policía Popular are vigilante self-defense groups that arose in the Gulf of Mexico and South Mexico regions between 2012 and 2013.

Jorge Luis Mendoza Cárdenas, commonly referred to by his alias La Garra, is a Mexican suspected drug lord and high-ranking leader of the Jalisco New Generation Cartel (CJNG), a criminal group based in Jalisco. Security forces suspect that La Garra heads the drug trafficking operations for the CJNG in the United States under Nemesio Oseguera Cervantes, the top leader of the criminal group. La Garra reportedly coordinates marijuana, cocaine, heroin, and methamphetamine shipments to Los Angeles, San Jose, Atlanta, and New York City from Mexico.

The Zetas Vieja Escuela is a Mexican criminal organization that splintered from Los Zetas. It was founded by José Guizar Valencia, alias "Z-43", along with other dissidents of the original organization.

Los Talibanes, known to a lesser extant as Los Nortes, are a Mexican criminal organization based in San Luis Potosí and Zacatecas.
