Central American migrant caravans, also known as the Viacrucis del migrante, are migrant caravans that travel from Central America to the Mexico–United States border to demand asylum in the United States. The largest and best known of these were organized by Pueblo Sin Fronteras that set off during Holy Week in early 2017 and 2018 from the Northern Triangle of Central America (NTCA), but such caravans of migrants began arriving several years earlier, and other unrelated caravans continued to arrive into late 2018.
