Tren de Aragua is an international criminal organization founded in Venezuela in 2009.
The gang was founded by Niño Guerrero in Venezuela's Tocorón prison, and it became the first Venezuelan criminal organization to expand internationally, playing a dominant role in human trafficking and smuggling in Latin America. The gang trafficked women across the Bolivia-Chile border and operated several cells in Chile, and it also had a heavy presence among Venezuelan refugees in the Peruvian city of Lima, established an increasingly widespread presence in the United States, and operated across Venezuela. On 11 July 2024, the US Treasury Department and White House designated Tren de Aragua a "transnational criminal organization."
