The Pa Cô people belong to the Mon-Khmer language group, often categorized together with the Tà Ôi ethnic group, but they possess many distinct characteristics regarding language, customs, and self-identity. In the Tà Ôi language, "Pa" means side and "Kô" means mountain, so Pa Cô translates to "people on the mountain side".
In Vietnam, the Pa Cô community is mainly concentrated in the two mountainous districts of Huong Hoa and Dakrong (Quang Tri province), along with a portion in A Luoi district (Thua Thien Hue province). They live alongside other ethnic groups such as the Van Kieu (Bru), Co Tu, and Tà Ôi. Their traditional life is closely tied to slash-and-burn farming, hunting, and gathering in the Truong Son mountains.
According to folk legend, the ancestors of the Pa Cô once lived in the plains, but due to their honesty during a citadel-building competition, they had to migrate to the mountains. Even as modern life brings changes, they maintain a tight-knit community lifestyle with traditional long stilt houses and a strong spirit of solidarity. The Pa Cô population in Vietnam is nearly 20,000 people, forming an important part of Quang Tri's diverse cultural tapestry.
