The Sinaloa Cartel () is a large and powerful drug trafficking transnational organized crime syndicate based in Culiacán, Sinaloa, Mexico, that specializes in illegal drug trafficking, money laundering, and murder. It has been Mexico's most dominant drug cartel since the 1990s.
The cartel's history is marked by evolution from a small crime syndicate to one of the most powerful and violent drug trafficking organizations in the world. Founded in the late 1960s by Pedro Avilés Pérez in Sinaloa, the cartel initially focused on smuggling cannabis into the United States. Pérez is credited with pioneering the use of aircraft for drug smuggling, laying the groundwork for large-scale trafficking operations. His organization was a training ground for the second generation of Sinaloan traffickers.
The Guadalajara Cartel was co-founded by Félix Gallardo between 1978 and 1980, marking the next phase in the cartel's history. Under Gallardo's leadership, the cartel controlled much of Mexico's drug trafficking corridors along the U.S. border throughout the 1980s. Following Gallardo's arrest in 1989, the cartel splintered into smaller organizations, including the Sinaloa Cartel.
Throughout the 1990s and 2000s, the Sinaloa Cartel, under the leadership of figures like Joaquín "El Chapo" Guzmán, significantly expanded its operations, establishing itself as one of the most powerful and influential criminal organizations in the world. The cartel was heavily involved in violent conflicts with rival groups such as the Tijuana Cartel, the Gulf Cartel, and later, the Jalisco New Generation Cartel (CJNG), as well as with Mexican federal forces.
During this period, the Sinaloa Cartel diversified its drug portfolio, becoming a major player in the global trade of cocaine, fentanyl, heroin, cannabis (marijuana), and methamphetamine. It developed sophisticated trafficking networks spanning across the Americas, Europe, and Asia, utilizing methods such as underground tunnels, maritime shipments, and corrupt border officials to smuggle narcotics into the United States and other markets. The cartel also became known for its strategic alliances, brutal enforcement tactics, and the ability to infiltrate local governments and law enforcement agencies, particularly in key trafficking corridors, further solidifying its position as a dominant force in the drug trade. Despite numerous arrests and seizures by law enforcement, the cartel has continued to operate, often employing sophisticated smuggling techniques, including tunnels under the US-Mexico border. It has operations in many world regions but primarily in the Mexican states of Sinaloa, Baja California, Durango, Sonora, and Chihuahua. and presence in other regions in Latin America, as well as cities across the U.S. The United States Intelligence Community considers the cartel to be the largest and most powerful drug trafficking organization in the world, perhaps more influential than Pablo Escobar's Medellín Cartel of Colombia during its prime. According to the National Drug Intelligence Center and other sources within the U.S. the Sinaloa Cartel is primarily involved in the distribution of cannabis (marijuana), cocaine, heroin, methamphetamine, fentanyl, and MDMA.
As of 2025, the cartel remains Mexico's most dominant drug cartel. After the arrest of Joaquín "El Chapo" Guzmán and his son Ovidio Guzmán López in 2016 and 2023 respectively, the cartel was headed by old-school leader Ismael "El Mayo" Zambada, as well as Guzmán's other sons, Jesús Alfredo Guzmán Salazar, Joaquín Guzmán López and Iván Archivaldo Guzmán Salazar,Tracking Mexico's Cartels in 2018 .

The cartel has had a significant impact regarding the war on drugs, both international and local politics, as well as in popular culture. Its influence extends beyond Mexico, with operations in the United States, Latin America, and as far as the Philippines. Despite the arrest of key leaders, the cartel remains a significant player in international drug trafficking, driven by demand for narcotics in the U.S. and around the world.
History
Avilés criminal organization Pedro Avilés Pérez was a pioneer drug lord in the Mexican state of Sinaloa in the late 1960s. He is considered to be, along with Vicente Carrillo Leyva, the first generation of major Mexican drug smugglers of cannabis (marijuana) who marked the birth of large-scale Mexican drug trafficking. He also pioneered the use of aircraft to smuggle drugs to the United States.
Second generation Sinaloan traffickers such as Rafael Caro Quintero, Ernesto Fonseca Carrillo, Miguel Ángel Félix Gallardo, Ismael Zambada García and Avilés Pérez' nephew Joaquín 'El Chapo' Guzmán would claim they learned all they knew about 'narcotraficantes' while serving in the Avilés organization. Pedro Avilés would eventually die in a shootout with federal police in September 1978 in Sinaloa.
Guadalajara Cartel Miguel Ángel Félix Gallardo, who co-founded the Guadalajara Cartel between 1978 and 1980, from then on controlled much of Mexico's drug-trafficking corridors along the United States border throughout the 1980s, only to be rivaled by the Gulf Cartel, which controlled some of eastern Mexico's drug trade.Shannon, Elaine (1988). Desperados: Latin drug lords, U.S. lawmen, and the war America can't win. New York: Viking. . Félix Gallardo divided up his "Federation" by 1987, just two years after the capture and murder of DEA agent Enrique Camarena Salazar when the threat from American law enforcement became much more pressing. This division of the organization in the late 1980s led to the cartel essentially being made up of several smaller cartels that controlled their own territories and trafficking corridors with their own bosses. This would make it less likely that the whole organization would be brought down all at once. One of these cartels (called plazas at the time) was Sinaloa, with the city of Culiacán acting as its headquarters. Alt URL In the late 1980s, the United States Drug Enforcement Administration (DEA) believed the Sinaloa Cartel was the largest drug trafficking organization operating in Mexico.
Gallardo was eventually arrested in 1989 and, while incarcerated, he remained one of Mexico's major traffickers, maintaining contact with his organization via mobile phone until he was transferred to a new maximum security prison in the early 1990s. At that point his nephews, the Arellano Félix brothers, left and further solidified the organization which came to be known as the Tijuana Cartel, while the Sinaloa Cartel continued to be run by former lieutenants Héctor Luis Palma Salazar, Juan Jose Esparragoza and Joaquín Guzmán Loera.
El Mayo and the Tijuana Cartel war During this time, Sinaloa was considered to be at a major disadvantage since they were forced to move much of their drug product through the Tijuana corridor, which often put them directly into conflict with the Arellanos. This eventually led to Ramón Arellano Félix killing two of Guzmán's associates, thus leading to a full-fledged war between the two organizations. It was around this period in the early 1990s when Guzmán brought in freelance trafficker Ismael Zambada García (a.k.a. El Mayo), particularly due to his exceptional ability to work with and coordinate with other traffickers. Throughout much of the 1990s, Ismael Zambada also helped grow and expand the cartel while Guzmán and Palma were incarcerated. Before getting directly involved with the Sinaloa Cartel, Ismael Zambada García was a farmer, freelancer and small-time drug trafficker who would sell mere kilograms of cannabis (marijuana) and heroin before eventually becoming acquainted with Mexico's more elite trafficking circles. By the mid-1990s, according to one court opinion, the Sinaloa organization was believed to be the size of the Medellín Cartel during its prime.
Zambada also helped Amado Carrillo Fuentes expand the Juárez Cartel in the state of Chihuahua and helped incorporate some of the remnants of the Juárez Cartel into the Sinaloa Cartel after Carrillo's death in 1997. The Sinaloa Cartel was therefore believed to be linked to the Juárez Cartel in a strategic alliance following the partnership of their rivals, the Gulf Cartel and Tijuana Cartel. Following the discovery of a tunnel system used to smuggle drugs across the Mexican/US border, the group has been associated with such means of trafficking. The war between the Sinaloa and Tijuana cartels was supposedly at its worst from 1992 to the year 2000 with family members of some of the cartel's leaders living in fear or "everyday like it was their last", as stated by Zambada's wife at the time. However, Zambada also used this conflict to his advantage since the Mexican government began to crack down primarily on the Tijuana Cartel, Mayo used this weakening of his rivals as an opportunity for Sinaloa to step up in the trafficking world. By around the year 2000, Zambada became recognized as one of the biggest and most powerful drug lords in Mexico, having built strong distribution networks from Colombia to the United States. Mayo's traditional major distribution hubs were allegedly in Chicago, Phoenix, Los Angeles, Atlanta, and Denver. El Mayo was also reportedly the one who sent a private helicopter for El Chapo after he escaped Puente Grande prison in 2001. The Sinaloa Cartel was partially splintered in 2008 when the Beltrán-Leyva brothers broke apart from the cartel.
The Sinaloa Cartel has been waging a war against the Tijuana Cartel (Arellano-Félix Organization) over the Tijuana smuggling route to the border city of San Diego, California. The rivalry between the two cartels dates back to the Miguel Ángel Félix Gallardo setup of Palma's family. Félix Gallardo, following his imprisonment, bestowed the Guadalajara Cartel on his nephews in the Tijuana Cartel. On 8 November 1992, Palma struck out against the Tijuana Cartel at a disco club in Puerto Vallarta, Jalisco, where eight Tijuana Cartel members were killed in the shootout, the Arellano-Félix brothers successfully escaping from the location with the assistance of David Barron Corona, a member of the Logan Heights Gang.
In retaliation, the Tijuana Cartel attempted to set up Guzmán at Guadalajara airport on 24 May 1993. In the shootout that followed, six civilians were killed by the hired gunmen from Logan Heights. The dead included Roman Catholic Cardinal Juan Jesús Posadas Ocampo. The church hierarchy originally believed Posadas was targeted as revenge for his strong stance against the drug trade. However, Mexican officials believe Posadas just happened to be caught in crossfire. The cardinal arrived at the airport in a white Mercury Grand Marquis town car, known to be popular amongst drug barons. Barron had received intelligence that Guzmán would be arriving in a white Mercury Grand Marquis town car. Evidence that runs counter to a mistake theory is that Posadas did not look anything like Guzmán, he was wearing a long black cassock and a large pectoral cross, and he was gunned down from only two feet away.
As of 2014, it is believed that the Tijuana Cartel, or at least a sizable majority of it, has been either absorbed or forced to ally with the Sinaloa Federation, in part due to a former high-ranking Tijuana member called Eduardo Teodoro Garcia Simental, alias "El Teo" or "Tres Letras" allying with the Federation.
