Pigtail macaques are widely distributed throughout Southeast Asia in the oriental biogeographic region. They are found in many countries including India (northeast), China (south), Indonesia (Borneo, Kalimantan, Sumatra), Bangladesh (east), Burma, Thailand, Laos, Cambodia, Vietnam, Malaysia (Malay Peninsula) (Cawthon Lang, 2009). Also found in Assam, Yunnan, Indochina, Bangka, and neighboring islands (Nowak, 1999). (Cawthon Lang, 2009; Nowak, 1999)
Macaque species are often capable of being introduced into other areas of the world with success. Pigtail macaques have been introduced in Singapore and the Natuna Islands (Nowak, 1999). (Nowak, 1999)
