The Tijuana Cartel or Arellano-Félix-Organization is a Mexican drug cartel based in Tijuana, Baja California, Mexico. Founded by the Arellano-Félix family, the cartel once was described as "one of the biggest and most violent criminal groups in Mexico". However, since the 2006 Sinaloa Cartel incursion in Baja California and the fall of the Arellano-Félix brothers, the Tijuana Cartel has been reduced to a few cells. In 2016, the organization became known as Cartel Tijuana Nueva Generación and began to align itself under the Jalisco New Generation Cartel, along with Beltrán Leyva Organization (BLO) to create an anti-Sinaloa alliance, in which the Jalisco New Generation Cartel heads. This alliance has since dwindled as the Tijuana, Jalisco New Generation, and Sinaloa cartels all now battle each other for trafficking influence in the city of Tijuana and the region of Baja California.
