The Triple Frontier is the tri-border area along the junction of Paraguay, Argentina, and Brazil known for its terrorist training camps. The Triple Frontier serves as a haven for car theft, counterfeiting, arms and drug trafficking, smuggling, money laundering, and other illicit activities.

Groups like Egypt's al-Gama'at al-Islamiyya, Islamic Jihad, Hizballah, and Al Qaeda are believed to draw some of their funding from activities in the Triple Frontier.
