Collared Peccaries are found in the Nearctic and Neotropical regions. The 14 subspecies occur from northern Argentina in South America, throughout Central America, and have spread into the southern Arizona, New Mexico, and Texas in the United States. In South and Central America, the Collared Peccary inhabits tropical rainforests. In the southern United States, herds occur in Saguaro deserts, where they prefer mesquite habitats with an abundance of prickly pear cacti. Collared Peccaries have also become common in residential areas, where they may rely on human handouts for food.
