National Route 19 (Vietnamese: Quốc lộ 19 [QL19] or Đường 19) runs across Vietnam roughly in line with the 14th parallel north. The route includes two segments: National Route 19 begins at Qui Nhơn and ends just short of the Vietnam-Cambodia border, while National Route 19B begins on the Qui Nhơn peninsula and joins Route 1 east of Phu Cat Airport.
