The Cham people (Cham: Urang Campa, Vietnamese: người Chăm or người Chàm, Khmer: ជន​ជាតិ​ចាម) are an ethnic group in Southeast Asia. They are concentrated between the Kampong Cham Province in Cambodia and central Vietnam's Phan Rang-Thap Cham, Phan Thiết, Ho Chi Minh City and An Giang areas. Approximately 4,000 Chams also live in Thailand; many of whom have moved south to the Pattani, Narathiwat, Yala, and Songkhla Provinces for work. Cham form the core of the Muslim communities in both Cambodia and Vietnam.
