Quduqian (Vietnamese: Khuất-đô-can;[1] Chinese: 屈都乾; pinyin: Qūdūqián) was the Chinese designation for an ancient kingdom, chiefdom, or a polity that perhaps located around Binh Dinh province, Central Vietnam, then became part of Champa Kingdoms.

[2] According to the Book of Jin, Quduqian situated 600 li or 186 miles/300 kilometers south of Boliao (波遼國,[3] Tam Kỳ).

Quduqian sent an embassy to the Jin court in Luoyang in 286 AD.
