The Giáp line (Vietnamese: chi Giáp; Hán tự: 支甲; chi can also be translated to as branch) was the ninth dynasty of Hùng kings of the Hồng Bàng period of Văn Lang (now Viet Nam). Starting approximately 1331 B.C., the line refers to the rule of Quân Lang and his successors, when the seat of government was centered at Phú Thọ.
